# 74LVC1G3157GV-TP

**TECH PUBLIC** · Analog Switches, Multiplexers · SOT-23-6

74LVC1G3157GV-TP from TECH PUBLIC, in a SOT-23-6. 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 | Y1 | passive | Independent analog input or output, connected to Z when S is high. |
| 2 | GND | power_in | Ground (0 V). |
| 3 | Y0 | passive | Independent analog input or output, connected to Z when S is low. |
| 4 | Z | passive | Common output or input of the SPDT switch. |
| 5 | VCC | power_in | Supply voltage, recommended operating range 1.5 V to 5.5 V (absolute maximum -0.3 V to +6.5 V). |
| 6 | S | input | Select input; low connects Y0 to Z, high connects Y1 to Z, control input range -0.3 V to 5.5 V. |
