74AHCT1G125DBVTG4

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOT-23-5

74AHCT1G125DBVTG4 from Texas Instruments, in a SOT-23-5. 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 OE input Output Enable input; when high, disables tri-state output Y to high-impedance state; when low, data passes from input A to output Y
2 A input Data input A with TTL-level thresholds VIL=0.8V and VIH=2V; input voltage range 0V to 5.5V
3 GND power_in Ground pin at circuit reference potential (0V)
4 Y tri_state Tri-state data output; passes buffered input A when OE is low with drive ±8mA at 5V; disabled to high-impedance state when OE is high; output voltage 0V to VCC
5 VCC power_in Positive power supply pin; operating range 4.5V to 5.5V; maximum quiescent current 10µA
