DESCRIPTION

The

DG406B

is

a

16-channel

single-ended

analog

multiplexer designed to connect one of sixteen inputs to a

common output as determined by a 4-bit binary address. The

DG407B selects one of eight differential inputs to a common

differential output. Break-before-make switching action

protects against momentary shorting of inputs.

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

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

operating temperature range.

Applications for the DG406B, DG407B 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 volts,

allowing operation with ± 20 V supplies. Additionally single

(12 V) supply operation is allowed. An epitaxial layer

prevents latchup.
