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.
