SN74LVC2G14

Texas Instruments · Logic Gate · SOT-23-6

The SN74LVC2G14 contains two Schmitt-trigger inverters in the LVC family. The input hysteresis cleans up slow or noisy signals into fast, clean logic edges, and the dual-gate package places two inverters at the board edge without a full package. It runs from 1.65 V to 5.5 V with 5 V-tolerant inputs.

Pinout

Pin Name Type Function
1 1A input Gate 1 Schmitt-trigger logic input. 5.5-V tolerant; positive-going threshold VT+ typ 1.7 V and negative-going threshold VT- typ 0.6 V at VCC = 3 V (hysteresis typ 1.1 V).
6 1Y output Gate 1 inverted output (Y = /A). Push-pull CMOS output, ±24 mA drive at VCC = 3 V, ±32 mA at VCC = 4.5 V.
3 2A input Gate 2 Schmitt-trigger logic input. 5.5-V tolerant; same hysteresis characteristics as 1A.
4 2Y output Gate 2 inverted output (Y = /A). Push-pull CMOS output, ±24 mA drive at VCC = 3 V.
2 GND power_in Ground reference (0 V). Connect directly to the board ground plane.
5 VCC power_in Supply voltage, 1.65 V to 5.5 V operating range. Bypass locally with a 0.1 µF ceramic capacitor to GND.
