Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SC-70-5

SN74AHC1G125DCK3 from Texas Instruments, in a SC-70-5. 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 OE input Output Enable input; output disabled (high impedance) when high, enabled when low.
2 A input Input A; data input passed to output Y when OE is low.
3 GND power_in Ground pin; reference voltage.
4 Y tri_state Output Y with tri-state capability; passes data from input A when OE is low, high-impedance state when OE is high.
5 VCC power_in Power supply pin; operating voltage range 2V to 5.5V.
