SN74HC138N

The SN74HC138N is a high-speed CMOS 3-to-8 line decoder/demultiplexer integrated circuit, part of the 74HC series by Texas Instruments. It operates with a wide supply voltage range of 2V to 6V, making it suitable for various digital logic applications. The device has three binary select inputs (A, B, C), three enable inputs (two active-low and one active-high), and eight active-low outputs. When enabled, the select inputs determine which one of the eight outputs will be driven low, while the others remain high.
Key features include low power consumption, high noise immunity, and typical propagation delay of about 14 ns at 5V. The SN74HC138N is widely used for memory address decoding, data routing, and other applications where decoding of binary data is needed. It comes in a standard DIP-16 package, making it easy to integrate into breadboards or through-hole PCBs for prototyping and development. Its versatility and reliability make it a popular choice in digital circuit design.
