SN74AHC1G126DRLR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOT-553-5

SN74AHC1G126DRLR from Texas Instruments, in a SOT-553-5. 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; when high enables true data pass-through from A to Y, when low places output Y in high-impedance state.
2 A input Input A; accepts input voltages to 5.5V for down-voltage translation applications.
3 GND power_in Ground pin; provides 0V reference for internal circuits and external signal connections.
4 Y tri_state Output Y; 3-state output with ±8mA drive capability at 5V and maximum ±25mA continuous output current.
5 VCC power_in Power supply pin; accepts operating voltage from 2V to 5.5V for device operation.
