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.
