SN74AHC1G125DC

lingxingic · Buffers, Drivers, Receivers, Transceivers · SOT-353

SN74AHC1G125DC from lingxingic, in a SOT-353. 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; a high level on OE puts output Y in the high-impedance state, and a low level enables the buffer (A to Y).
2 A input Data input of the non-inverting buffer; recommended input voltage range is 0 V to 5.5 V (absolute maximum -0.5 V to 7.0 V).
3 GND power_in Ground (0 V).
4 Y tri_state Buffered data output with three-state capability; output current is limited to ±25 mA (absolute maximum) and output voltage must stay between 0 V and VCC.
5 VCC power_in Supply voltage; recommended 2.0 V to 5.5 V for SN74AHC1G125 and 4.5 V to 5.5 V for SN74AHCT1G125 (absolute maximum 7.0 V).
