JSMSEMI · Inverters · SOP-14

74HC14 from JSMSEMI, 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 input. Positive-going threshold VT+ = 2.38 V typ and negative-going threshold VT- = 1.40 V typ at VCC=4.5 V (hysteresis VH ~0.98 V).
2 1Y output Schmitt-trigger inverter 1 output (inverted 1A). Push-pull CMOS output, IOH/IOL rated at 4.0 mA (VCC=4.5 V) / 5.2 mA (VCC=6.0 V).
3 2A input Schmitt-trigger inverter 2 input.
4 2Y output Schmitt-trigger inverter 2 output (inverted 2A).
5 3A input Schmitt-trigger inverter 3 input.
6 3Y output Schmitt-trigger inverter 3 output (inverted 3A).
7 GND power_in Ground reference (0 V). System ground return for all six inverter channels.
8 4Y output Schmitt-trigger inverter 4 output (inverted 4A).
9 4A input Schmitt-trigger inverter 4 input.
10 5Y output Schmitt-trigger inverter 5 output (inverted 5A).
11 5A input Schmitt-trigger inverter 5 input.
12 6Y output Schmitt-trigger inverter 6 output (inverted 6A).
13 6A input Schmitt-trigger inverter 6 input.
14 VCC power_in Positive supply. Recommended 2.0 V to 6.0 V (5.0 V typ); absolute max 7 V. Quiescent supply current ICC <= 2 uA at VCC=6.0 V, Tamb=25 C. Bypass with 100 nF close to the pin.
