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
as V_DD = 12 V, V_SS = –12 V), and unsymmetric
supplies (such as V_DD = 12 V, V_SS = –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.
