The SN74HCT04N part is a hex inverter manufactured by Texas Instruments. It contains six independent gates that can each invert the logic state of the input. Each gate is designed so that when the input is low, the output is high, and vice versa. This part is able to handle both TTL logic and CMOS logic levels, making it suitable for a wide range of applications. The SN74HCT04N is widely used in digital circuits such as counter/timers, alarms, or multiplexers. It has a 4.5 to 5.5V supply voltage and a -55 to 125°C temperature range. The SN74HCT04N has industry standard pinouts and is available in a variety of plastic packages including PDIPs, SOICs, SOPs, and TSSOPs.
