3 Description

The TMUX622x are complementary metal-oxide

semiconductor (CMOS) switch in a dual 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 TMUX622x supports bidirectional analog

and digital signals on the source (Sx) and drain (D)

pins ranging from VSS to VDD.

The TMUX622x can be enabled or disabled by

controlling the SEL pins, turning on signal path 1 (S1

to D1) or signal path 2 (S2 to D2). All logic control

inputs support logic levels from 1.8 V to VDD, allowing

for both TTL and CMOS logic compatibility 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.

The TMUX622x is part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents, 50 pA, allowing

them to be used in high precision measurement

applications.
