74HCT32D

Nexperia · Logic Gates · SOIC-14

74HCT32D from Nexperia, in a SOIC-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 include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
2 1B input Data input 1B of gate 1; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
3 1Y output Data output 1Y of gate 1, the logic OR of 1A and 1B; output current limited to ±25 mA.
4 2A input Data input 2A of gate 2; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
5 2B input Data input 2B of gate 2; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
6 2Y output Data output 2Y of gate 2, the logic OR of 2A and 2B; output current limited to ±25 mA.
7 GND power_in Ground (0 V) reference for all voltages on the device.
8 3Y output Data output 3Y of gate 3, the logic OR of 3A and 3B; output current limited to ±25 mA.
9 3A input Data input 3A of gate 3; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
10 3B input Data input 3B of gate 3; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
11 4Y output Data output 4Y of gate 4, the logic OR of 4A and 4B; output current limited to ±25 mA.
12 4A input Data input 4A of gate 4; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
13 4B input Data input 4B of gate 4; inputs include clamp diodes, so a current-limiting resistor can be used when the input is driven above VCC (input clamp current limited to ±20 mA).
14 VCC power_in Supply voltage; recommended 4.5 V to 5.5 V for the 74HCT32 (absolute maximum -0.5 V to +7 V).
