3 Description
The TMUX6236 is a complementary metal-oxide
semiconductor (CMOS) switch with two 2:1 switches.
The device works well with dual supplies (±4.5V to
±18V), a single supply (4.5V to 36V), or asymmetric
supplies (such as VDD = 12V, VSS = –5V). 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
1.8V 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.
