8-Channel/4-Channel Fault-Protected Analog Multiplexers
ADG508F/ADG509F
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 Low on resistance (270 Ω typical) Fast switching times
tON: 230 ns maximum tOFF: 130 ns maximum Low power dissipation (3.3 mW maximum) Fault and overvoltage protection (−40 V to +55 V) Break-before-make construction TTL and CMOS compatible inputs
APPLICATIONS
Existing multiplexer applications (both fault-protected and nonfault-protected)
New designs requiring multiplexer functions
GENERAL DESCRIPTION
The ADG508F and ADG509F are CMOS analog multiplexers, with the ADG508F comprising eight single channels and the ADG509F comprising four differential channels.
