HGSEMI · Logic Gates · DIP-14

74HC08N from HGSEMI, in a DIP-14. 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 Data input 1A of gate 1; inputs must stay between GND and VCC (recommended VCC 2.0 V to 6.0 V).
2 1B input Data input 1B of gate 1; inputs must stay between GND and VCC (recommended VCC 2.0 V to 6.0 V).
3 1Y output Data output 1Y of gate 1, logic function Y = A AND B.
4 2A input Data input 2A of gate 2; inputs must stay between GND and VCC (recommended VCC 2.0 V to 6.0 V).
5 2B input Data input 2B of gate 2; inputs must stay between GND and VCC (recommended VCC 2.0 V to 6.0 V).
6 2Y output Output 2Y of gate 2, logic function Y = A AND B; the datasheet labels this pin 输入输出 (input/output), which is treated here as the gate output per the truth table.
7 GND power_in Ground reference (0 V) for the device.
