SN74HCT04NSR

Texas Instruments · Inverters · SOIC-14-208mil

SN74HCT04NSR from Texas Instruments, in a SOIC-14-208mil. 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 Inverter 1 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V at VCC 4.5 V to 5.5 V, and must be tied to VCC or GND if unused.
2 1Y output Inverter 1 output (Y = not A), drives up to 10 LSTTL loads with ±4 mA output drive at 5 V.
3 2A input Inverter 2 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V, and must be tied to VCC or GND if unused.
4 2Y output Inverter 2 output (Y = not A), with ±4 mA output drive at 5 V.
5 3A input Inverter 3 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V, and must be tied to VCC or GND if unused.
6 3Y output Inverter 3 output (Y = not A), with ±4 mA output drive at 5 V.
7 GND power_in Ground reference for the device.
8 4Y output Inverter 4 output (Y = not A), with ±4 mA output drive at 5 V.
9 4A input Inverter 4 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V, and must be tied to VCC or GND if unused.
10 5Y output Inverter 5 output (Y = not A), with ±4 mA output drive at 5 V.
11 5A input Inverter 5 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V, and must be tied to VCC or GND if unused.
12 6Y output Inverter 6 output (Y = not A), with ±4 mA output drive at 5 V.
13 6A input Inverter 6 input; TTL-compatible with VIH min 2 V and VIL max 0.8 V, and must be tied to VCC or GND if unused.
14 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended (absolute maximum 7 V), with a 0.1-µF bypass capacitor recommended close to the pin.
