CD74HC154EN

The CD74HC154EN is an Integrated Circuit (IC) component that belongs to the 74HC series of high-speed CMOS logic family. It is a 4-to-16 line decoder/demultiplexer with active HIGH output enable. Here is an overview and some key features of the CD74HC154EN: 1. Functionality: The CD74HC154EN takes a 4-bit binary input and decodes it into one of the 16 output lines. It functions as a demultiplexer, allowing for the selection of a single output line based on the binary input. 2. High-Speed Operation: The "HC" in the CD74HC154EN denotes high-speed CMOS technology. It offers improved speed compared to traditional TTL devices and operates with a wide range of signal frequencies. 3. Active High Output Enable: The CD74HC154EN includes an active HIGH output enable (OE) pin. When OE is set to logic HIGH, all output pins are disabled, regardless of the input conditions. This feature allows for easy data flow control. 4. Easy Cascade Connection: Multiple CD74HC154EN chips can be easily cascaded together to create larger decoding applications. By connecting the output pins of one IC to the input pins of the next, it is possible to extend the decoding capacity beyond 16 lines
