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
x
) 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.
