SN74LVC1G32

Texas Instruments · Logic Gate · SOT-23-5

The SN74LVC1G32 is a single 2-input OR gate in the LVC family. Its output goes high when either input is high. The single-gate package places one gate at the board edge without a full quad package, running from 1.65 V to 5.5 V with 5 V-tolerant inputs.

Pinout

Pin Name Type Function
1 A input Logic input A of the 2-input OR gate. Accepts 0-5.5V regardless of VCC.
2 B input Logic input B of the 2-input OR gate. Accepts 0-5.5V regardless of VCC.
3 GND power_in Ground reference (0 V).
4 Y output Push-pull logic output Y = A + B. ±24 mA drive at 3.3V VCC.
5 VCC power_in Positive supply voltage. Recommended operating range approximately 1.65V-5.5V.
