GENERAL DESCRIPTION
The ADG438F and ADG439F are CMOS analog multiplexers, with the ADG438F comprising eight single channels and the ADG439F comprising four differential channels. These multiplexers provide fault protection.
FEATURES
All switches off with power supply off
Analog output of on channel clamped within power supplies
if an overvoltage occurs
Latch-up proof construction
Fast switching times
tON 250 ns maximum
tOFF 150 ns maximum
Fault and overvoltage protection: −40 V to +55 V
Break-before-make construction
TTL- and CMOS-compatible inputs
APPLICATIONS
