Break-before-make switching action protects against momentary crosstalk of adjacent input signals. The DG428 selects one of eight single-ended inputs to a common output, while the DG429 selects one of four differential inputs to a common differential output. An on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. An enable (EN) function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices. All control inputs, address (Ax) and enable (EN) are TTL compatible over the full specified operating temperature range. The silicon-gate CMOS process enables operation over a wide range of supply voltages. The absolute maximum voltage rating is extended to 44 V. Additionally, single supply operation is also allowed and an epitaxial layer prevents latchup. On-board TTL-compatible address latches simplify the digital interface design and reduce board space in bus-controlled systems such as data acquisition systems, process controls, avionics, and ATE.

J, 06-Sep-99 5-10 DG428/429 Vishay Siliconix DETAILED DESCRIPTION APPLICATIONS The internal structure of the DG428/DG429 includes a 5-V logic interface with input protection circuitry followed by a latch, level shifter, decoder and finally the switch constructed with parallel n- and p-channel MOSFETs (see Figure 1). Bus Interfacing The DG428/DG429 minimize the amount of interface hardware between a microprocessor system bus and the analog system being controlled or measured. The internal TTL compatible latches give these multiplexers write-only memory, that is, they can be programmed to stay in a particular switch state (e.g., switch 1 on) until the microprocessor determines it is necessary to turn different switches on or turn all switches off (see Figure 10). The input latches become transparent when WR is held low; therefore, these multiplexers operate by direct command of the coded switch state on A2, A1, A0. In this mode the DG428 is identical to the popular DG408. The same is true of the DG429 versus the popular DG409. During system power-up, RS would be low, maintaining all eight switches in the off state. After RS returned high the DG428 maintains all switches in the off state. When the system program performs a write operation to the address assigned to the DG428, the address decoder provides a CS active low signal which is gated with the WRITE (WR) control signal. At this time the data on the DATA BUS (that will determine which switch to close) is stabilizing. When the WR signal returns to the high state, (positive edge) the input latches of the DG428 save the data from the DATA BUS. The coded information in the A0, A1, A2 and EN latches is decoded and the appropriate switch is turned on. The EN latch allows all switches to be turned off under program control. This becomes useful when two or more DG428s are cascaded to build 16-line and larger multiplexers. The input protection on the logic lines A0, A1, A2, EN and control lines WR, RS shown in Figure 1 minimizes susceptibility to ESD that may be encountered during handling and operational transients. The logic interface is a CMOS logic input with its supply voltage from an internal +5 V reference voltage. The output of the input inverter feeds the data input of a D type latch. The level sensitive D latch continuously places the DX input signal on the QX output when the WR input is low, resulting in transparent latch operation. As soon as WR returns high the latch holds the data last present on the Dn input, subject to the "Minimum Input Timing Requirements" table. Following the latches the Qn signals are level shifted and decoded to provide proper drive levels for the CMOS switches. This level shifting ensures full on/off switch operation for any analog signal level between the V+ and V- supply rails. The EN pin is used to enable the address latches during the WR pulse. It can be hard wired to the logic supply or to V+ if one of the channels will always be used (except during a reset) or it can be tied to address decoding circuitry for memory mapped operation. The RS pin is used as a master reset. All latches are cleared regardless of the state of any other latch or control line. The WR pin is used to transfer the state of the address control lines to their latches, except during a reset or when EN is low (see Truth Tables). +15 V S1 V+ "15 V Analog Inputs Data Bus A0, A1, A2, EN DG428 Processor System Bus RESET +5 V S8 WRITE Address Bus Address Decoder - 15 V WR V- D Analog Output RS FIGURE 10.Bus Interface Document Number: 70063 S-52433--Rev.
