74HC138 3-to-8 line Decoder/Demultiplexer SMD IC
The 74HC138 3-to-8 Line Decoder/Demultiplexer SMD IC is a high-speed CMOS device designed for digital logic applications, particularly useful in decoding binary data into one of eight possible outputs. This IC efficiently expands the number of addressable output lines from just three select inputs, making it ideal for memory addressing, data routing, and control signal demultiplexing in microprocessors and microcontrollers. With a surface-mount (SMD) package, the 74HC138 is compact and well-suited for applications requiring space optimization on printed circuit boards (PCBs), such as in compact consumer electronics, communication devices, and embedded systems. The 74HC138 is built with three binary address inputs (A, B, and C), which can decode up to eight unique combinations. These inputs select one of the eight outputs (Y0 to Y7), enabling it to go low (active). All other outputs remain high, ensuring a clean, unambiguous signal for each input combination. Additionally, the IC has three enable inputs (G1, G2A, and G2B), which allow the device to be enabled or disabled independently, providing flexibility for multi-stage decoding or selective activation in more complex circuits.
