3 Description

The MUX508 and MUX509 (MUX50x) are modern,

complementary metal-oxide semiconductor (CMOS),

analog multiplexers (muxes). The MUX508 offers 8:1

single-ended channels; whereas, the MUX509 offers

differential 4:1 (8:2) channels. The MUX508 and

MUX509 work equally well with either dual supplies

(±5 V to ±18 V) or a single supply (10 V to 36 V).

They also perform well with symmetric supplies (such

inputs

have

TTL-logic

compatible

thresholds,

ensuring both TTL and CMOS logic compatibility

when operating in the valid supply voltage range.

The MUX508 and MUX509 have very low on and off

leakage currents, allowing these multiplexers to

switch signals from high input impedance sources

with minimal error. A low supply current of 45 µA

allows for use in portable applications.
