The DG428/DG429 analog multiplexers have on-chip address

and control latches to simplify design in microprocessor based

applications. 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 (A

(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.
