SN74LS02N

lingxingic · Gates · DIP-14

SN74LS02N from lingxingic, 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 1Y output Gate 1 data output (NOR of 1A and 1B).
2 1A input Gate 1 data input A; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
3 1B input Gate 1 data input B; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
4 2Y output Gate 2 data output (NOR of 2A and 2B).
5 2A input Gate 2 data input A; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
6 2B input Gate 2 data input B; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
7 GND power_in Ground (0 V).
8 3A input Gate 3 data input A; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
9 3B input Gate 3 data input B; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
10 3Y output Gate 3 data output (NOR of 3A and 3B).
11 4A input Gate 4 data input A; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
12 4B input Gate 4 data input B; input has built-in clamp diode so it can be tied to voltages above VCC through a current-limiting resistor.
13 4Y output Gate 4 data output (NOR of 4A and 4B).
14 VCC power_in Supply voltage; recommended 2.0 V to 6.0 V, absolute maximum -0.5 V to +7 V.
