GENERAL DESCRIPTION
comprising four differential channels. These multiplexers provide
fault protection. Using a series n-channel, p-channel, and
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 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 flows. This
protects not only the multiplexer and the circuitry driven by the
multiplexer, but also protects the sensors or signal sources which
drive the multiplexer.
The ADG438F switches one of eight inputs to a common output
as determined by the 3-bit binary address lines, A0, A1, and A2.
The ADG439F 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.
stand continuous voltage inputs up to 40 V or +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-channel and n-channel MOSFETs thereby
preventing latch-up.
7.
Improved Off Isolation. Trench isolation enhances the
