Texas Instruments · Buffers, Drivers, Receivers, Transceivers · TSSOP-14

SN74LV4T125PWR from Texas Instruments, 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 input for buffer 1; low active, high sets output to high-impedance.
2 1A input Logic input for buffer 1; 5.5 V overvoltage tolerant for level translation.
3 1Y tri_state Three-state output for buffer 1; sources/sinks up to 16 mA at 5.0 V VCC.
4 2OE input Output enable input for buffer 2; low active, high sets output to high-impedance.
5 2A input Logic input for buffer 2; 5.5 V overvoltage tolerant for level translation.
6 2Y tri_state Three-state output for buffer 2; sources/sinks up to 16 mA at 5.0 V VCC.
7 GND power_in Ground pin; establishes reference potential for all signal and power levels.
8 3Y tri_state Three-state output for buffer 3; sources/sinks up to 16 mA at 5.0 V VCC.
9 3A input Logic input for buffer 3; 5.5 V overvoltage tolerant for level translation.
10 3OE input Output enable input for buffer 3; low active, high sets output to high-impedance.
11 4Y tri_state Three-state output for buffer 4; sources/sinks up to 16 mA at 5.0 V VCC.
12 4A input Logic input for buffer 4; 5.5 V overvoltage tolerant for level translation.
13 4OE input Output enable input for buffer 4; low active, high sets output to high-impedance.
14 VCC power_in Power supply pin; accepts 1.6 V to 5.5 V for flexible level translation.
