74hc138 pinout

The 74HC138 is a 3-to-8 line decoder/demultiplexer with a built-in 3-to-8 active low decoder with three binary weighted address inputs (A0, A1, A2), and a single active low enable input (E1) making it easy to use in a control system. It also features an active low enable input (E2 and E3), making it possible to use all eight outputs independently. The 74HC138 is designed to perform the 3-to-8 line decoding function in high-speed digital systems. This makes it an ideal choice for data communications, systems, and memory chip select address decoding. Its low power consumption also makes it suitable for battery-powered electronic devices. The 74HC138 pinout consists of 16 pins with the necessary inputs and outputs clearly labeled, allowing for easy integration into a variety of electronic circuits. This decoder/demultiplexer is widely used in various electronic projects and is a fundamental component in digital systems design.
