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 or dual 4:1 single-ended 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 as VDD = 12 V, VSS = –12 V), and

unsymmetric supplies (such as VDD = 12 V, VSS =

–5 V). All digital 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.
