The “74HC04D” is an inverter gate, also known as a hex inverter. It is a digital logic gate that takes an input signal and produces the logical NOT (complement) of that input.
This part number is commonly associated with various manufacturers, including NXP Semiconductors, Texas Instruments, ON Semiconductor, and others. Different manufacturers may produce chips with the same part number, and they generally have similar functionality and characteristics.
Features
High-speed CMOS technology.
Wide operating voltage range (typically 2V to 6V).
Low power consumption.
Compatibility with TTL (Transistor-Transistor Logic) inputs.
A hex inverter typically contains six individual inverter gates within a single IC package.
