DESCRIPTION

The DG408 is an 8-channel single-ended analog multiplexer
designed to connect one of eight inputs to a common output
as determined by a 3-bit binary address (A0, A1, A2). The
DG409 is a dual 4-channel differential analog multiplexer
designed to connect one of four differential inputs to a common
dual output as determined by its 2-bit binary address (A0, A1).
Break-before-make switching action protects against
momentary crosstalk between adjacent channels.

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.

Applications for the DG408/409 include high speed data
acquisition, audio signal switching and routing, ATE systems,
and avionics. High performance and low power dissipation
make them ideal for battery operated and remote
instrumentation applications.

Designed in the 44-V silicon-gate CMOS process, the
absolute maximum voltage rating is extended to 44 V.
Additionally, single supply operation is also allowed. An
epitaxial layer prevents latchup.
