DESCRIPTION  
Isolation  
The MPC508A is an 8-channel single-ended analog  
multiplexer and the MPC509A is a 4-channel differential  
multiplexer.

The MPC508A and MPC509A multiplexers have input  
overvoltage protection. Analog input voltages may exceed  
either power supply voltage without damaging the device or  
disturbing the signal path of other channels. The protection  
circuitry assures that signal fidelity is maintained even under  
fault conditions that would destroy other multiplexers. Analog  
inputs can withstand 70VPP signal levels and standard ESD  
tests. Signal sources are protected from short circuits should  
multiplexer power loss occur; each input presents a 1k  
resistance under this condition. Digital inputs can also sustain  
continuous faults up to 4V greater than either supply voltage.

These features make the MPC508A and MPC509A ideal for  
use in systems where the analog signals originate from  
external equipment or separately powered sources.

Isolation  
The MPC508A and MPC509A are fabricated with Burr-  
Browns dielectrically isolated CMOS technology. The  
multiplexers are available in plastic DIP and plastic SOIC  
packages. Temperature range is 40°C to +85°C.
