3 Description

The TMUX620x is a complementary metal-oxide

semiconductor (CMOS) in a single channel, 1:1

(SPST) configuration. The device works with a single

supply (4.5 V to 36 V), dual supplies (±4.5 V to ±18

V), or asymmetric supplies (such as VDD = 12 V, VSS

= –5 V). The TMUX620x supports bidirectional analog

and digital signals on the source (S) and drain (D) pin

ranging from VSS to VDD.

The TMUX620x can be enabled or disabled by

controlling the SEL pin. When disabled, both signal

path switches are off. All logic control inputs support

logic levels from 1.8 V to VDD, which is compatible for

both TTL and CMOS logic when operating in the valid

supply voltage range. Fail-Safe Logic circuitry allows

voltages on the control pins to be applied before

the supply pin, protecting the device from potential

damage.
