GENERAL DESCRIPTION
The ADG508A and ADG509A are CMOS monolithic analog
multiplexers with eight channels and dual four channels, respec-
tively. The ADG508A switches one of eight inputs to a common
output, depending on the state of three binary addresses and an
enable input. The ADG509A switches one of four differential
inputs to a common differential output, depending on the state
of two binary addresses and an enable input. Both devices have
TTL and 5 V CMOS logic-compatible digital inputs.
The ADG508A and ADG509A are designed on an enhanced
LC²MOS process that gives an increased signal capability of VSS
to VDD and enables operation over a wide range of supply voltages.
The devices can comfortably operate anywhere in the 10.8 V to
16.5 V single- or dual-supply range. These multiplexers also
feature high switching speeds and low RON.

PRODUCT HIGHLIGHTS
1. Single-/Dual-Supply Specifications with a Wide Tolerance.
The devices are specified in the 10.8 V to 16.5 V range for
both single and dual supplies.
2. Extended Signal Range. The enhanced LC²MOS processing
results in a high breakdown and an increased analog signal
range of VSS to VDD.
3. Break-Before-Make Switching. Switches are guaranteed
break-before-make so that input signals are protected
against momentary shorting.
4. Low Leakage. Leakage currents in the range of 20 pA make
these multiplexers suitable for high precision circuits.
