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.  
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.

Package Option*  
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 differen-  
tial 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.

PRODUCT HIGHLIGHTS  
1. Fault Protection.  
*N = Plastic DIP; P = Plastic Leaded Chip Carrier (PLCC); RN = 0.15" Small  
Outline IC (SOIC), RW = 0.3" Small Outline IC (SOIC).  
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.  
*Patent Pending.
