SN74HCS125PWR

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

SN74HCS125PWR 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 Channel 1 Output Enable, active low; Schmitt-trigger input that drives output 1Y to high-impedance when high
2 1A input Channel 1 input A; Schmitt-trigger input
3 1Y tri_state Channel 1 output Y; tri-state output, high-impedance when 1OE is high, otherwise buffers 1A input
4 2OE input Channel 2 Output Enable, active low; Schmitt-trigger input that drives output 2Y to high-impedance when high
5 2A input Channel 2 input A; Schmitt-trigger input
6 2Y tri_state Channel 2 output Y; tri-state output, high-impedance when 2OE is high, otherwise buffers 2A input
7 GND power_in Ground
8 3Y tri_state Channel 3 output Y; tri-state output, high-impedance when 3OE is high, otherwise buffers 3A input
9 3A input Channel 3 input A; Schmitt-trigger input
10 3OE input Channel 3 Output Enable, active low; Schmitt-trigger input that drives output 3Y to high-impedance when high
11 4Y tri_state Channel 4 output Y; tri-state output, high-impedance when 4OE is high, otherwise buffers 4A input
12 4A input Channel 4 input A; Schmitt-trigger input
13 4OE input Channel 4 Output Enable, active low; Schmitt-trigger input that drives output 4Y to high-impedance when high
14 VCC power_in Positive supply voltage, 2V to 6V
