HGSEMI · Inverters · SOP-14

74HC14M from HGSEMI, in a SOP-14. 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 inverter 1 data input. VT+ typ 2.38 V, VT- typ 1.40 V at VCC=4.5 V, giving ~1.0 V of hysteresis for clean transitions from slow inputs.
2 1Y output Schmitt-trigger inverter 1 data output. Inverted logic level of 1A; drives ±4.0 mA at VCC=4.5 V.
3 2A input Schmitt-trigger inverter 2 data input.
4 2Y output Schmitt-trigger inverter 2 data output. Inverted logic level of 2A.
5 3A input Schmitt-trigger inverter 3 data input.
6 3Y output Schmitt-trigger inverter 3 data output. Inverted logic level of 3A.
7 GND power_in System ground reference (0 V).
8 4Y output Schmitt-trigger inverter 4 data output. Inverted logic level of 4A.
9 4A input Schmitt-trigger inverter 4 data input.
10 5Y output Schmitt-trigger inverter 5 data output. Inverted logic level of 5A.
11 5A input Schmitt-trigger inverter 5 data input.
12 6Y output Schmitt-trigger inverter 6 data output. Inverted logic level of 6A.
13 6A input Schmitt-trigger inverter 6 data input.
14 VCC power_in Positive supply, 2.0 V to 6.0 V (5.0 V typ). Absolute max +7 V. Bypass with a 0.1 uF ceramic capacitor to GND close to the pin.
