Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-14-208mil

SN74AHCT125DBR from Texas Instruments, in a SSOP-14-208mil. 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 1OE input Output enable for gate 1; passes input to output when low, high-impedance when high
2 1A input Gate 1 input
3 1Y tri_state Gate 1 output; 3-state output enabled when 1OE is low
4 2OE input Output enable for gate 2; passes input to output when low, high-impedance when high
5 2A input Gate 2 input
6 2Y tri_state Gate 2 output; 3-state output enabled when 2OE is low
7 GND power_in Ground pin
8 3Y tri_state Gate 3 output; 3-state output enabled when 3OE is low
9 3A input Gate 3 input
10 3OE input Output enable for gate 3; passes input to output when low, high-impedance when high
11 4Y tri_state Gate 4 output; 3-state output enabled when 4OE is low
12 4A input Gate 4 input
13 4OE input Output enable for gate 4; passes input to output when low, high-impedance when high
14 VCC power_out Power supply pin; 4.5V to 5.5V recommended operating range
