SN74LVC2G14DCK3

Texas Instruments · Inverters · SC-70-6

SN74LVC2G14DCK3 from Texas Instruments, in a SC-70-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1A input Gate 1 logic signal input; the inputs are 5.5-V tolerant, so they accept voltages up to 5.5 V regardless of VCC.
2 GND power_in Ground reference pin for the device.
3 2A input Gate 2 logic signal input; the inputs are 5.5-V tolerant, so they accept voltages up to 5.5 V regardless of VCC.
4 2Y output Gate 2 inverted signal output, rated for ±24 mA drive at 3.3 V VCC.
5 VCC power_in Supply pin; operating supply range is 1.65 V to 5.5 V and each VCC pin should be bypassed with a capacitor close to the pin.
6 1Y output Gate 1 inverted signal output, rated for ±24 mA drive at 3.3 V VCC.
