3 Description

The TMUX7219 is a complementary metal-oxide

semiconductor (CMOS) switch with latch-up immunity

in a single channel, 2:1 (SPDT) configuration. The

device works 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 TMUX7219

supports bidirectional analog and digital signals on the

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

VDD.

The TMUX7219 can be enabled or disabled by

controlling the EN pin. When disabled, both signal

path switches are off. When enabled, the SEL pin

can be used to turn on signal path 1 (S1 to D) or

signal path 2 (S2 to D). All logic control inputs support

logic levels from 1.8 V to VDD, ensuring 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 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.
