SN74HC02PW

lingxingic · Logic Gates · TSSOP-14

SN74HC02PW from lingxingic, in a TSSOP-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 1Y output Data output of NOR gate 1; per the function table, 1Y is H only when both 1A and 1B are L.
2 1A input Data input A of NOR gate 1, which is part of the 2-input NOR function Y = NOT(A OR B).
3 1B input Data input B of NOR gate 1, which is part of the 2-input NOR function Y = NOT(A OR B).
4 2Y output Data output of NOR gate 2; per the function table, 2Y is H only when both 2A and 2B are L.
5 2A input Data input A of NOR gate 2, which is part of the 2-input NOR function Y = NOT(A OR B).
6 2B input Data input B of NOR gate 2, which is part of the 2-input NOR function Y = NOT(A OR B).
7 GND power_in Ground reference (0 V); the datasheet states GND = 0 V for all tested conditions.
8 3A input Data input A of NOR gate 3, which is part of the 2-input NOR function Y = NOT(A OR B).
9 3B input Data input B of NOR gate 3, which is part of the 2-input NOR function Y = NOT(A OR B).
10 3Y output Data output of NOR gate 3; per the function table, 3Y is H only when both 3A and 3B are L.
11 4A input Data input A of NOR gate 4, which is part of the 2-input NOR function Y = NOT(A OR B).
12 4B input Data input B of NOR gate 4, which is part of the 2-input NOR function Y = NOT(A OR B).
13 4Y output Data output of NOR gate 4; per the function table, 4Y is H only when both 4A and 4B are L.
14 VCC power_in Supply voltage; the recommended range is 2.0 V to 6.0 V for SN74HC02 and 4.5 V to 5.5 V for SN74HCT02.
