Nexperia · Buffer/Driver/Transceiver · TSSOP-14

74ALVC125PW from Nexperia, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OE input Output enable for buffer 1, active LOW. Drive LOW to enable the 1Y output; drive HIGH to place 1Y in high-impedance 3-state. Schmitt-trigger input, 3.6 V tolerant.
2 1A input Data input for buffer 1. Non-inverting buffer path: 1Y follows 1A when 1OE is LOW. Schmitt-trigger input, overvoltage tolerant to 3.6 V.
3 1Y tri_state Bus output for buffer 1. Drives 1A when 1OE is LOW; high-impedance OFF-state when 1OE is HIGH. Rated for ±24 mA drive at VCC = 3.0 V.
4 2OE input Output enable for buffer 2, active LOW. Drive LOW to enable the 2Y output; drive HIGH to place 2Y in high-impedance 3-state. Schmitt-trigger input, 3.6 V tolerant.
5 2A input Data input for buffer 2. Non-inverting buffer path: 2Y follows 2A when 2OE is LOW. Schmitt-trigger input, overvoltage tolerant to 3.6 V.
6 2Y tri_state Bus output for buffer 2. Drives 2A when 2OE is LOW; high-impedance OFF-state when 2OE is HIGH. Rated for ±24 mA drive at VCC = 3.0 V.
7 GND power_in Ground reference (0 V). Connect to the system ground plane.
8 3Y tri_state Bus output for buffer 3. Drives 3A when 3OE is LOW; high-impedance OFF-state when 3OE is HIGH. Rated for ±24 mA drive at VCC = 3.0 V.
9 3A input Data input for buffer 3. Non-inverting buffer path: 3Y follows 3A when 3OE is LOW. Schmitt-trigger input, overvoltage tolerant to 3.6 V.
10 3OE input Output enable for buffer 3, active LOW. Drive LOW to enable the 3Y output; drive HIGH to place 3Y in high-impedance 3-state. Schmitt-trigger input, 3.6 V tolerant.
11 4Y tri_state Bus output for buffer 4. Drives 4A when 4OE is LOW; high-impedance OFF-state when 4OE is HIGH. Rated for ±24 mA drive at VCC = 3.0 V.
12 4A input Data input for buffer 4. Non-inverting buffer path: 4Y follows 4A when 4OE is LOW. Schmitt-trigger input, overvoltage tolerant to 3.6 V.
13 4OE input Output enable for buffer 4, active LOW. Drive LOW to enable the 4Y output; drive HIGH to place 4Y in high-impedance 3-state. Schmitt-trigger input, 3.6 V tolerant.
14 VCC power_in Positive supply voltage, 1.65 V to 3.6 V recommended operating range (absolute max 4.6 V). Decouple to GND with a local ceramic capacitor.
