SN74AHC125PWR

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

SN74AHC125PWR from Texas Instruments, in a TSSOP-14. 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; when low, passes input 1A to output 1Y; when high, output is high-impedance.
2 1A input Gate 1 input data signal.
3 1Y tri_state Gate 1 tri-state output; passes 1A when 1OE is low, high-impedance when 1OE is high.
4 2OE input Output enable for gate 2; when low, passes input 2A to output 2Y; when high, output is high-impedance.
5 2A input Gate 2 input data signal.
6 2Y tri_state Gate 2 tri-state output; passes 2A when 2OE is low, high-impedance when 2OE is high.
7 GND power_in Ground connection, 0V reference.
8 3Y tri_state Gate 3 tri-state output; passes 3A when 3OE is low, high-impedance when 3OE is high.
9 3A input Gate 3 input data signal.
10 3OE input Output enable for gate 3; when low, passes input 3A to output 3Y; when high, output is high-impedance.
11 4Y tri_state Gate 4 tri-state output; passes 4A when 4OE is low, high-impedance when 4OE is high.
12 4A input Gate 4 input data signal.
13 4OE input Output enable for gate 4; when low, passes input 4A to output 4Y; when high, output is high-impedance.
14 VCC power_in Power supply voltage pin, operating range 2V to 5.5V.
