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.

VDD | 13 | 11 | P | Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between VDD and GND. |
VSS | 5 | 3 | P | Negative power supply. This pin is the most negative power-supply potential. In single-supply applications, this pin can be connected to ground. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between VSS and GND. |
Thermal Pad | — | The thermal pad is not connected internally. There is no requirement to electrically connect this pad. If connected, however, it is recommended that the pad be left floating or tied to GND. |
