SN74AUP1T87DCKR from Texas Instruments, in a SC-70-5. 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 A input Schmitt-trigger logic input A of the XNOR gate, accepting 1.8-V, 2.5-V or 3.3-V levels with input voltage range 0 V to 3.6 V; unused inputs must be held at VCC or GND.
2 B input Schmitt-trigger logic input B of the XNOR gate, accepting 1.8-V, 2.5-V or 3.3-V levels with input voltage range 0 V to 3.6 V; unused inputs must be held at VCC or GND.
3 GND power_in Ground reference for the device, with continuous current through VCC or GND limited to ±50 mA.
4 Y output XNOR output Y = A XNOR B with CMOS levels referenced to VCC, rated for 4 mA drive at VCC = 3 V (3.1 mA at 2.3 V).
5 VCC power_in Supply voltage pin, recommended operating range 2.3 V to 3.6 V (absolute maximum 4.6 V).
