Texas Instruments · Logic Gates · PDIP-14

CD74HCT00E from Texas Instruments, in a PDIP-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 Input A of gate 1; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
2 1B input Input B of gate 1; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
3 1Y output Balanced CMOS push-pull output of gate 1 (Y = A · B); unused outputs should be left disconnected.
4 2A input Input A of gate 2; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
5 2B input Input B of gate 2; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
6 2Y output Balanced CMOS push-pull output of gate 2 (Y = A · B); unused outputs should be left disconnected.
7 GND power_in Ground reference for the device.
8 3Y output Balanced CMOS push-pull output of gate 3 (Y = A · B); unused outputs should be left disconnected.
9 3A input Input A of gate 3; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
10 3B input Input B of gate 3; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
11 4Y output Balanced CMOS push-pull output of gate 4 (Y = A · B); unused outputs should be left disconnected.
12 4A input Input A of gate 4; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
13 4B input Input B of gate 4; TTL-compatible CMOS input that must not be left floating, with VIL(max) 0.8 V and VIH(min) 2 V at VCC 4.5 V to 5.5 V.
14 VCC power_in Positive supply, 4.5 V to 5.5 V recommended operating range; a 0.1-µF bypass capacitor is recommended close to this pin.
