GENERAL DESCRIPTION
The ADG508F, ADG509F, and ADG528F
multiplexers, with the ADG508F and ADG528F comprising
eight single channels and the ADG509F comprising four
differential channels. These multiplexers provide fault protec-
tion. 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 −40 V to
+55 V. During fault conditions, the multiplexer input (or out-
put) 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 and ADG528F switch 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. The ADG528F has on-
chip address and control latches that facilitate microprocessor

Fault Protection.
The ADG508F/ADG509F/ADG528F can withstand
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.
On channel turns off while fault exists.
Low R
Fast switching times.
Break-before-make switching.
Switches are guaranteed break-before-make so that input
signals are protected against momentary shorting.
Trench isolation eliminates latch-up.
A dielectric trench separates the p and n-channel
MOSFETs thereby preventing latch-up.
