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

DESCRIPTION

The

DG408LE,

DG409LE

are

monolithic

analog

multiplexers / demultiplexers designed to operate on

single and dual supplies. Single supply voltage ranges from

3 V to 16 V while dual supply operation is recommended

with ± 3 V to ± 8 V.

The DG408LE 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 DG409LE 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 to protect 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.

The DG408LE, DG409LE feature low on-resistance, fast

switching time, and low leakage. They are ideal for data

acquisition, control and automation, test instrument, and

healthcare products. The DG408LE, DG409LE has an

internal regulator powers the logic circuit. Such design

reduces device power consumption and makes them ideal

for battery operated applications.

The DG408LE, DG409LE are available in TSSOP16,

SOIC16, and QFN16 packages.

FEATURES
