SN74LVC1G14

Texas Instruments · Logic Gate · SOT-23-5

The SN74LVC1G14 is a single Schmitt-trigger inverter in the LVC family. Its input hysteresis cleans up slow or noisy signals into fast, clean logic edges, and the single-gate package drops in exactly where one inverter is needed. It runs from 1.65 V to 5.5 V and is 5 V tolerant on the input.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection. May be tied to any signal or voltage source (including ground); TI recommends soldering to the board for mechanical retention.
2 A input Schmitt-trigger signal input. VT+ ≈ 1.5V and VT- ≈ 0.84V at VCC=3V (hysteresis ΔVT ≈ 0.56V typ). Accepts input voltages up to 5.5V regardless of VCC (5V-tolerant).
3 GND power_in Ground reference (0V) for the device.
4 Y output Inverted Schmitt-trigger output, Y = /A. Push-pull CMOS drive of ±24 mA at VCC=3.3V (±32 mA at 4.5V).
5 VCC power_in Positive supply, 1.65V to 5.5V operating (1.5V min for data retention only). Ioff supports partial-power-down: outputs are disabled when the device is unpowered to prevent backflow.
