The TMUX622x are complementary metal-oxide semiconductor (CMOS) switch in a dual channel, 1:1 (SPST) configuration. The device works with a single supply (4.5 V to 36 V), dual supplies (±4.5 V to ±18 V), or asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX622x supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD.
The TMUX622x can be enabled or disabled by controlling the SEL pins, turning on signal path 1 (S1 to D1) or signal path 2 (S2 to D2). All logic control inputs support logic levels from 1.8 V 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.
The TMUX622x is part of the precision switches and multiplexers family of devices. These devices have very low on and off leakage currents, 50 pA, allowing them to be used in high precision measurement applications.

NAME | NO. | ||
S1 | 1 | I/O | Source pin 1. Can be an input or output. |
S2 | 2 | I/O | Source pin 2. Can be an input or output. |
N.C. | 3 | — | No internal connection. Can be shorted to GND or left floating. |
GND | 4 | P | Ground (0 V) reference |
VDD | 5 | P | Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1 µF to 10 µF between VDD and GND. |
SEL2 | 6 | I | Logic control input, has internal pull-down resistor. Controls the switch connection. For more information, see Section 7.5. |
SEL1 | 7 | I | Logic control input, has internal pull-down resistor. Controls the switch connection. For more information, see Section 7.5. |
VSS | 8 | 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 0.1 µF to 10 µF between VSS and GND. |
D2 | 9 | I/O | Drain pin 2. Can be an input or output. |
D1 | 10 | I/O | Drain pin 1. Can be an input or output. |
