74HC154 IC 4-to-16 Decoder/Demultiplexer DIP-24 74HC154

Product Overview

The CD74HCT154 is a high-speed CMOS 4-to-16 line decoder/demultiplexer. It is designed to decode four binary-weighted inputs into one of sixteen mutually exclusive outputs. When the device is enabled, the output corresponding to the binary input is driven low, while all other outputs remain high. It features two enable inputs that facilitate easy cascading or demultiplexing applications.
