ADG509FBRN 8 Channel 4 Channel Fault Protected Analog Multiplexers

GENERAL DESCRIPTION

The ADG508F and ADG509F are CMOS analog multi-
plexers,with the ADG508F comprising eight single
channels and the ADG509F comprising four differential
channels. These multiplexers provide fault protection.
Using a series n-channel,p-channel,n-channel MOSFET
structure, both device and signal source protection is
provided in the event of an overvoltage or power loss.
The multiplexer can withstand continuous overvoltage
inputs from −40V to +55V. During fault conditions with
power supplies off,the multiplexer input (or output)
appears as an open circuit and only a few nanoamperes
of leakage current will flow. This protects not only
the multiplexer and the circuitry driven by the multiplexer,
but also protects the sensors or signal sources that drive
the multiplexer.
The ADG508F switches one of eight inputs to a common output
as determined by the 3-bit binary address lines A0,A1,and A2.
The ADG509F switches one of four differential inputs to a
common differential output as determined by the 2-bit binary
address lines A0 and A1. An EN input on each device is used
to enable or disable the device.When disabled, all channels are
switched off.

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 ¦¸ typical)
Fast switching times
t ON: 230 ns maximum
t OFF: 130 ns maximum
Low power dissipation (3.3 mW maximum)
Fault and overvoltage protection (−40V to +55V)
Break-before-make construction
TTL and CMOS compatible inputs

APPLICATIONS

Existing multiplexer applications
(both fault-protected and nonfault-protected)
New designs requiring multiplexer functions
