44-V, latch-up immune, 1:1 (SPST) 2 channel precision switch with 1.8V Logic (active high)

The TMUX722x are complementary metal-oxide semiconductor (CMOS) switches

with latch-up immunity in a dual channel, 1:1 (SPST) configuration. These devices

work with a single supply (4.5 V to 44 V), dual

supplies (±4.5 V to ±22 V), or asymmetric supplies (such

as VDD = 12 V, VSS = –5 V). The TMUX722x supports bidirectional analog and digital signals on the

source (Sx) and drain (D) pins ranging from VSS to

VDD.

The TMUX722x 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. For more information, see .

The TMUX72xx family provides latch-up

immunity, preventing undesirable high current events between parasitic structures

within the device typically caused by overvoltage events. A latch-up condition

typically continues until the power supply rails are turned off and can lead to

device failure. The latch-up immunity feature allows the TMUX72xx family of switches

and multiplexers to be used in harsh environments.
