The 74HC04; 74HCT04 is a hex inverter. The inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits Complies with JEDEC standard JESD7A Input levels: For 74HC04: CMOS level For 74HCT04: TTL level ESD protection: The 7404 is a hex inverter chip, which means it's composed of 6 independent inverter gates. Each gate is composed 1 input and 1 output. The 7404 should be fed a minimum voltage of 4.5V and a maximum voltage of 5.5V. The pinout of the 7404 is shown below. You can see based on the pinout that there are 6 inverter gates. Each one has 1 input and 1 ...
