3 Description

The TMUX6219 is a complementary metal-oxide

semiconductor (CMOS) switch in a single channel, 2:1

(SPDT) configuration. The device works with single

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

V), or asymmetric supplies (such as VDD = 5 V, VSS

= −8 V). The TMUX6219 supports bidirectional analog

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

pins ranging from VSS to VDD.

The TMUX6219 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 TMUX6219 is part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications.
