Low-Voltage, Single and Dual Supply, 8 to 1 Multiplexer, Dual 4 to 1 Multiplexer and a Triple SPDT Analog Switches
The Intersil ISL84051, ISL84052, ISL84053 devices are precision, bidirectional, analog switches configured as a 8 channel multiplexer/demultiplexer (ISL84051), a dual differential 4 channel multiplexer/demultiplexer (ISL84052) and a triple single pole/double throw (SPDT) switch (ISL84053) designed to operate from a single +2V to +12V supply or from a 2V to 6V supply. All devices have an inhibit pin to simultaneously open all signal paths. ON resistance is 60 with a 5V supply and 125 with a single +5V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 0.1nA at +25oC or 5nA at +85oC with a 5V supply. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single +3.3V and +5V supply or dual 5V supplies. The ISL84051 is a 8 to 1 multiplexer device. The ISL84052 is a dual 4 to 1 multiplexer device. The ISL84053 is a committed triple SPDT, which is perfect for use in 2-to-1 multiplexer applications. Table 1 summarizes the performance of this family.

ISL84051, ISL84052, ISL84053 Detailed Description
The ISL84051, ISL84052, ISL84053 analog switches offer precise switching capability from a bipolar 2V to 6V or a single 2V to 12V supply with low on-resistance (60) and high speed operation (tON = 50ns, tOFF = 40ns). The devices are especially well suited to portable battery powered equipment thanks to the low operating supply voltage (2V), low power consumption (3W), low leakage currents (5nA max). High frequency applications also benefit from the wide bandwidth, and the very high off isolation and crosstalk rejection.
Power-Supply Considerations
The ISL8405X construction is typical of most CMOS analog switches, in that they have three supply pins: V+, V-, and GND. V+ and V- drive the internal CMOS switches and set their analog voltage limits, so there are no connections between the analog signal path and GND. Unlike switches with a 13V maximum supply voltage, the ISL8405X 15V maximum supply voltage provides plenty of room for the 10% tolerance of 12V supplies (6V or 12V single supply), as well as room for overshoot and noise spikes. This family of switches performs equally well when operated with bipolar or single voltage supplies. The minimum recommended supply voltage is 2V or 2V. It is important to note that the input signal range, switching times, and onresistance degrade at lower supply voltages. Refer to the electrical specification tables and Typical Performance curves for details. V+ and GND power the internal logic (thus setting the digital switching point) and level shifters. The level shifters convert the logic levels to switched V+ and V- signals to drive the analog switch gate terminals.
Supply Sequencing And Overvoltage Protection
With any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to V- (see Figure 8). To prevent forward biasing these diodes, V+ and V- must be applied before any input signals, and input signal voltages must remain between V+ and V-. If these conditions cannot be guaranteed, then one of the following two protection methods should be employed. Logic inputs can easily be protected by adding a 1k resistor in series with the input (see Figure 8). The resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not applicable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low RON switch, so two small signal diodes can be added in series with the supply pins to provide overvoltage protection for all pins (see Figure 8). These additional diodes limit the analog signal from 1V below V+ to 1V above V-. The low leakage current performance is unaffected by this approach, but the switch resistance may increase, especially at low supply voltages.

Logic-Level Thresholds
V+ and GND power the internal logic stages, so V- has no affect on logic thresholds. This switch family is TTL compatible (0.8V and 2.4V) over a V+ supply range of 2.7V to 10V. At 12V the VIH level is about 3.5V. This is still below the CMOS guaranteed high output minimum level of 4V, but noise margin is reduced. For best results with a 12V supply, use a logic family that provides a VOH greater than 4V. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation.
High-Frequency Performance
In 50 systems, signal response is reasonably flat even past 100MHz (see Figure 17). Figure 17 also illustrates that the frequency response is very consistent over varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feed through from a switch's input to its output. Off Isolation is the resistance to this feed through, while Crosstalk indicates the amount of feed through from one switch to another. Figure 18 details the high Off Isolation and Crosstalk rejection provided by this family. At 10MHz, Off Isolation is about 55dB in 50 systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease Off Isolation and Crosstalk rejection due to the voltage divider action of the switch OFF impedance and the load impedance.

Leakage Considerations
Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and V-. One of these diodes conducts if any analog signal exceeds V+ or V-. Virtually all the analog leakage current comes from the ESD diodes to V+ or V-. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and V- pins constitutes the analog-signalpath leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog signal paths and GND.
