Texas Instruments 74HCT04 Hex Inverter Logic IC, 14-Pin DIP

The Texas Instruments SN74HCT04N is a high-speed CMOS logic IC configured as a hex inverter. It contains six independent inverter circuits within a single 14-pin dual in-line package (DIP). Each circuit performs the standard Boolean inversion function (Y = A̅) in positive logic, making it a fundamental building block for digital circuit design.

This device is engineered for reliable operation within a 4.5V to 5.5V supply voltage range, making it ideal for 5V TTL-compatible systems. A key feature is its very low power consumption, with a maximum ICC of just 20µA, which helps minimise overall system energy use. Despite its low power draw, it offers robust output drive capability, able to source or sink up to ±4mA and drive up to 10 low-power Schottky TTL (LSTTL) loads.

The 74HCT04 boasts excellent performance characteristics, including a typical propagation delay (tpd) of 13ns, ensuring fast signal processing. Its inputs are TTL-voltage compatible, allowing for easy interfacing with a wide range of legacy and modern digital components, while maintaining a very low maximum input current of 1µA. This combination of speed, drive strength, and compatibility makes it a versatile choice for numerous digital applications.

Constructed in a robust DIP package, it is suitable for use across a broad industrial temperature range from -40°C to +85°C, ensuring reliable operation in demanding environments. The through-hole design facilitates easy prototyping and integration into breadboards or printed circuit boards (PCBs).
