The SN74HC04N is a hex inverter buffer from Texas Instruments. The device features six independent inverters, each of which performs the logic inverter function. It has a true (non-inverting) output enable input for easy paralleling of outputs and fast enable/disable times. This part is powered by either a 5-volt or a 3.3-volt supply and is a member of the 74HC/HCT/HCU/HCMOS logic family. It is designed to operate at up to 4.5MHz, with power consumption of only 1.5 mW per line, making it ideal for applications that require low power operation. The SN74HC04N is available in standard 14-pin PDIP or SOIC packages, making it easy to integrate with existing designs.
