lingxingic · Inverters · SOT-23-5

SN74LVC1G14DB from lingxingic, in a SOT-23-5. 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 n.c. unconnected Not connected (不连接) per the datasheet pin table; no function is assigned to this pin.
2 A input Data input of the Schmitt-trigger inverter; the recommended input voltage range is 0 V to 5.5 V (VI, section 3.2).
3 GND power_in Ground (0 V) reference; all electrical characteristics are specified with GND = 0 V.
4 Y output Inverted data output; the output drive is rated at ±24 mA at VCC = 3.0 V and the absolute maximum output current is ±50 mA (IO).
5 VCC power_in Supply voltage; the recommended operating range is 1.65 V to 5.5 V (VCC, section 3.2), with an absolute maximum of -0.5 V to +6.5 V.
