# SN74LVC1G125DBVR-TP

**TECH PUBLIC** · Buffers, Drivers, Receivers, Transceivers · SOT-23-5

SN74LVC1G125DBVR-TP 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 | G | input | Active-low output enable input; Y is high impedance (Z) when G is high and follows A when G is low (inputs 5.5 V tolerant). |
| 2 | A | input | Buffer data input A, 5.5 V tolerant, with unused inputs to be tied to VCC or GND. |
| 3 | GND | power_in | Ground pin. |
| 4 | Y | tri_state | 3-state buffer output Y, drives ±24 mA (min) at VCC = 3.0 V and goes high impedance when G is high. |
| 5 | VCC | power_in | Supply voltage pin, operating range 1.65 to 5.5 V (absolute maximum -0.5 to 6.0 V). |
