# TPTMUX1102DBVR

**TECH PUBLIC** · Analog Switches, Multiplexers · SOT-23-5

TPTMUX1102DBVR from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D | passive | Normally opened port of the analog switch; signal range -0.3 to 5.5 V recommended, connected to S when SEL is low. |
| 2 | S | passive | Common port of the analog switch; switch voltage rated -0.3 to +6.5 V absolute maximum. |
| 3 | GND | power_in | Ground. |
| 4 | SEL | input | Digital control pin to connect D to S; low (VIL max 0.4 V at VDD 1.5-3.3 V, 0.6 V at 3.3-5.5 V) turns switch ON, high turns it OFF; 1.8 V logic compatible, -0.3 to 5.5 V recommended. |
| 5 | VDD | power_in | Supply voltage, recommended operating range 1.6 to 5.5 V, absolute maximum -0.3 to +6.5 V. |
