onsemi · Inverters · TSOP-5

MC74HC1G14DTT1G from onsemi, in a TSOP-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 NC unconnected No connect pin; not internally connected per the pin assignment.
2 IN A input Schmitt-trigger inverter input; recommended input voltage 0.0 to VCC.
3 GND power_in Ground pin (0 V reference).
4 OUT Y output Inverter output; drives 2.0 mA (IOH = IOL) and is the logical inverse of IN A.
5 VCC power_in Positive supply; recommended operating range 2.0 V to 6.0 V (absolute maximum 7.0 V).
