GENERAL DESCRIPTION
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 overvolt-
age inputs from 40 V to +55 V. 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.

PRODUCT HIGHLIGHTS
1.
continuous voltage inputs from 40 V to +55 V. When a
fault occurs due to the power supplies being turned off, all
the channels are turned off and only a leakage current of a
few nanoamperes flows.
2.
On channel saturates while fault exists.
3.
Low RON.
4.
Fast switching times.
5.
Break-before-make switching. Switches are guaranteed
break-before-make so that input signals are protected
against momentary shorting.
6.
Trench isolation eliminates latch-up. A dielectric trench
separates the p and n-channel MOSFETs thereby
preventing latch-up.
