8-Ch/Dual 4-Ch High-Performance CMOS Analog Multiplexers

DG408, DG409

Vishay Siliconix

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 (Ax)

and enable (EN) are TTL compatible over the full specified

operating temperature range.

Applications for the DG408, DG409 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.
