GENERAL DESCRIPTION

The ADG508F, ADG509F and ADG528F are CMOS analog

multiplexers, the ADG508F and ADG528F 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 –40 V to +55 V. During

fault conditions, 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 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 inter-

facing. An EN input on each device is used to enable or disable

the device. When disabled, all channels are switched OFF.

New Designs Requiring Multiplexer Functions

The ADG508F/ADG509F/ADG528F can withstand con-

tinuous 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.

Switches are guaranteed break-before-make so that input

signals are protected against momentary shorting.

A dielectric trench separates the p and n-channel MOSFETs

thereby preventing latch-up.
