SN74LV1T32DBVR

Texas Instruments · Gates · SOT-23-5

SN74LV1T32DBVR from Texas Instruments, in a SOT-23-5. 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 A input Input A of the 2-input OR gate. Reduced-threshold CMOS input with 5V-tolerance (accepts signals up to 5.5V regardless of VCC). VIH(min) ranges from ~0.94V at 1.8V VCC to ~2.02V at 5.0V VCC.
2 B input Input B of the 2-input OR gate. Reduced-threshold CMOS input with 5V-tolerance (accepts signals up to 5.5V regardless of VCC). Must not be left floating - tie to VCC or GND via 10kΩ if unused.
3 GND power_in Ground reference (0 V). Return for VCC supply and logic reference.
4 Y output OR-gate output: Y = A OR B, referenced to VCC (balanced CMOS push-pull). Drive strength scales with VCC: 3mA @ 1.8V, 5mA @ 2.5V, 7mA @ 3.3V, 8mA @ 5.0V.
5 VCC power_in Positive supply, 1.8V to 5.5V recommended (absolute max 7.0V). Also sets the output HIGH voltage level and the input switching thresholds. Bypass with 0.1µF (and optional 1µF in parallel) placed close to the pin.
