15kV ESD-Protected, Low-Voltage, Quad, SPST, CMOS Analog Switches MAX4620/MAX4630/MAX4640
General Description
The MAX4620/MAX4630/MAX4640 low-voltage, highESD-protected, quad, single-pole/single-throw (SPST) analog switches are pin-compatible replacements for the industry-standard 74HC4066 analog switch. The normally open (NO) and normally closed (NC) pins are protected against 15kV electrostatic discharge (ESD) without latchup or damage. Each switch can handle Rail-to-Rail(R) analog signals. The off-leakage current is 0.5nA at +25C. These analog switches are suitable for low-distortion audio applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements (0.5W), require less board space, and are more reliable than mechanical relays. Each device is controlled by TTL/CMOS input voltage levels and is bilateral. These switches feature guaranteed operation from a +2V to +12V single supply, making them ideal for use in battery-powered applications. The on-resistance is 70 max, matched between switches to 0.5 (typ), and flat (2 typ) over the specified signal range. The MAX4620 has four NO switches, the MAX4630 has four NC switches, and the MAX4640 has two NO and two NC switches. These devices are available in 14-pin TSSOP, SO, and DIP packages.

The MAX4620/MAX4630/MAX4640 are quad SPST CMOS analog switches with circuitry providing 15kV ESD protection on the NO and NC pins. The CMOS switch construction provides rail-to-rail signal handling while consuming virtually no power. Each of the four switches is independently controlled by a TTL/CMOSlevel-compatible digital input.

Applications Information
Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always sequence V+ on first, followed by the logic inputs, NO/NC, or COM.

Operating Considerations for High-Voltage Supply
The MAX4620/MAX4630/MAX4640 are capable of +12V single-supply operation with some precautions. The absolute maximum rating for V+ is 13V (referenced to GND). When operating near this region, bypass V+ with a minimum 0.1F capacitor to ground as close to the IC as possible.

15kV ESD Protection
The MAX4620/MAX4630/MAX4640 are 15kV ESD-protected at the NC/NO terminals. To accomplish this, bidirectional SCRs are included on-chip between these terminals. When the voltages at these terminals go Beyond-the-RailsTM, the corresponding SCR turns on in a few nanoseconds and bypasses the surge safely to ground. This method is superior to using diode clamps to the supplies because unless the supplies are very carefully decoupled through low ESR capacitors, the ESD current through the diode clamp could cause a significant spike in the supplies. This may damage or compromise the reliability of any other chip powered by those same supplies. There are diodes from NC/NO to the supplies in addition to the SCRs. There is a resistance in series with each of these diodes to limit the current into the supplies during an ESD strike. The diodes protect these terminals from overvoltages that are not a result of ESD strikes. These diodes also protect the device from improper power-supply sequencing. Once the SCR turns on because of an ESD strike, it continues to be on until the current through it falls below its "holding current." The holding current is typically 110mA in the positive direction (current flowing into the NC/NO terminal) at room temperature (see Supply Current vs. Temperature in the Typical Operating Characteristics). Design the system so that any sources connected to NC/NO are current limited to a value below the holding current to ensure the SCR turns off when the ESD event is finished and normal operation is resumed. Also, keep in mind that the holding current varies significantly with temperature. The worst case is at +85C when the holding currents drop to 70mA. Since this is a typical number to guarantee turn-off of the SCRs under all conditions, the sources connected to these terminals should be current limited to not more than half this value. When the SCR is latched, the voltage across it is approximately 3V, depending on the polarity of the pin current. The supply voltages do not appreciably affect the holding current. The sources connected to the COM side of the switches do not need to be current limited since the switches turn off internally when the corresponding SCR(s) latches. Even though most of the ESD current flows to GND through the SCRs, a small portion of it goes into V+. Therefore, it is a good idea to bypass the V+ with 0.1F capacitors directly to the ground plane. ESD protection can be tested in various ways. Transmitter outputs and receiver inputs are characterized for protection to the following: * 15kV using the Human Body Model * * 8kV using the Contact Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2) 15kV using the Air-Gap Discharge method specified in IEC 1000-4-2 (formerly IEC 801-2)
ESD Test Conditions Contact Maxim Integrated Products for a reliability report that documents test setup, methodology, and results. Human Body Model Figure 6 shows the Human Body Model, and Figure 7 shows the waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which can be discharged into the test device through a 1.5k resistor. IEC 1000-4-2 The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to ICs. The MAX4620/MAX4630/MAX4640 enable the design of equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without additional ESD protection components. The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2. Because series resistance is lower in the IEC 1000-4-2 ESD test model (Figure 8), the ESD withstand voltage measured to this standard is generally lower than that measured using the Human Body Model. Figure 9 shows the current waveform for the 8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test. The Air-Gap test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.
