7404 IC Introduction

The IC 7404 belongs to a six inverter chip, which has a large working voltage range, wide operating conditions, and its output is directly connected to CMOS, NMOS and TTL.

What is 7404 IC

The SN7404 IC consists of six independent inverter gates, each consisting of an input and an output. Reverse phase is one of its main functions. In digital logic, inverter gate is the logic gate to realize logic inversion. The inverter circuit inputs and outputs to it a voltage representing the opposite logic level. If the applied input is low, the output becomes high and vice versa. The inverter can be constructed using a single NMOS transistor or a single PMOS transistor coupled to a resistor.

SN7404 hexadecimal inverter is widely used in the circuit, the most common application is to invert the applied input signal.
