SN74LVC3G14DCUR

Texas Instruments · Inverters · VSSOP-8-0.5mm

SN74LVC3G14DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 1A input Schmitt-trigger logic input for inverter channel 1. High-impedance CMOS input with input hysteresis (~0.4 V at VCC = 3.3 V). Absolute-max input voltage −0.5 V to 6.5 V; 5-V tolerant regardless of VCC.
2 1Y output Inverted CMOS output for channel 1 (1Y = NOT 1A). Push-pull output; typical drive ±24 mA at 3.3 V (rail-to-rail swing to VCC/GND).
3 GND power_in Ground reference (0 V) for the device. Connect directly to the system ground plane with a low-impedance path; also serves as the return for the VCC decoupling capacitor.
4 2A input Schmitt-trigger logic input for inverter channel 2. High-impedance CMOS input with input hysteresis (~0.4 V at VCC = 3.3 V). 5-V tolerant regardless of VCC.
5 2Y output Inverted CMOS output for channel 2 (2Y = NOT 2A). Push-pull output; typical drive ±24 mA at 3.3 V.
6 3Y output Inverted CMOS output for channel 3 (3Y = NOT 3A). Push-pull output; typical drive ±24 mA at 3.3 V.
7 3A input Schmitt-trigger logic input for inverter channel 3. High-impedance CMOS input with input hysteresis (~0.4 V at VCC = 3.3 V). 5-V tolerant regardless of VCC.
8 VCC power_in Positive supply pin. Operating range 1.65 V to 5.5 V. Decouple to GND with a 0.1 µF ceramic capacitor placed as close as practical to the pin.
