74AHCT1G126W5-7

Diodes Incorporated · Buffer/Driver/Transceiver · SOT-25

74AHCT1G126W5-7 from Diodes Incorporated, in a SOT-25. 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. Active-HIGH 3-state control: when HIGH, the buffer drives Y from A; when LOW, Y enters high-impedance (Z). TTL-compatible input (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5-5.5 V).
2 A input Data input to the non-inverting buffer. TTL-compatible logic input (VIH = 2.0 V min, VIL = 0.8 V max) with Schmitt-trigger action for slower input transitions.
3 GND power_in Ground reference (0 V). Continuous current through GND rated at -50 mA maximum.
4 Y tri_state Data output. Non-inverting 3-state buffer output driving ±8 mA at VCC = 5.0 V. Enters high-impedance (Z) when OE is LOW.
5 VCC power_in Supply voltage input. Recommended operating range 4.5 V to 5.5 V (absolute max -0.5 V to 6.5 V). Continuous current through VCC rated at 50 mA maximum.
