74hc138 pinout

The 74HC138 is a 3-to-8 line decoder/demultiplexer with a 3-bit binary input that activates one of eight outputs based on the input. This versatile integrated circuit is commonly used in digital electronics and microcontroller projects to demultiplex data from a microcontroller to multiple output lines, or to decode a binary input signal into a specific output. The 74HC138 features three enable inputs (G1, G2A, and G2B) for easy cascading and expansion of the decoder, making it suitable for applications requiring multiple demultiplexers or decoders. With its low power consumption, high noise immunity, and wide supply voltage range, the 74HC138 is a reliable and efficient solution for digital logic applications. The pinout of the 74HC138 includes 16 pins, with various inputs and outputs along with power supply and ground connections. Whether it's for hobbyist projects, educational purposes, or professional applications, the 74HC138 is a versatile and essential component for digital logic design.
