74LCX138MTCX – FSC

Overview

The onsemi 74LCX138MTCX is a high-performance 1-of-8 decoder/demultiplexer designed for efficient address decoding and data routing in complex digital systems. Its key operational characteristic is its ability to translate a 3-bit binary input into one of eight active-low outputs, facilitating precise control over multiple subsystems. A critical design consideration when implementing this device is managing the propagation delay from enable input to output, as this can significantly impact system timing margins, especially in high-speed applications where minimizing skew is paramount.
