3 Description

The TMUX6236 is a complementary metal-oxide

semiconductor (CMOS) switch with two 2:1 switches.

The device works well with dual supplies (±4.5 V to

±18 V), a single supply (4.5 V to 36 V), or asymmetric

supplies (such as VDD = 12 V, VSS = –5 V). The

TMUX6236 supports bidirectional analog and digital

signals on the source (Sx) and drain (D) pins ranging

from VSS to VDD.

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.
