What is CD74HC154MG4 used for?
The CD74HC154MG4 is used in address decoding for memory systems, I/O port expansion, and demultiplexing applications in microprocessor-based systems where a 4-bit binary address must select one of 16 output lines. It is well-suited for chip-select generation in embedded systems, LED matrix driving, and relay multiplexing applications. The dual enable inputs allow easy cascading for larger decoder trees without additional external gating logic.

Frequently Asked Questions
What does the CD74HC154MG4 do and how many outputs does it have?
The CD74HC154MG4 is a 4-line to 16-line decoder/demultiplexer that converts a 4-bit binary input into one of 16 active-low output lines. Only one output is active at a time corresponding to the selected binary address, making it ideal for address decoding and chip-select generation in digital systems.
What are the enable inputs on the CD74HC154MG4 and how are they used?
The CD74HC154MG4 has two active-low enable inputs (E1 and E2) that must both be low for any output to be active. When either enable input is high, all outputs remain inactive. These enable inputs allow easy cascading of multiple CD74HC154 devices to create larger 5-line to 32-line or larger decoders.
What logic family does the CD74HC154MG4 belong to and what supply voltage does it use?
The CD74HC154MG4 belongs to the HC/UH (High-speed CMOS) logic family, which typically operates from 2V to 6V supply voltage with TTL-compatible input thresholds. This family provides fast switching speeds comparable to TTL logic while consuming significantly lower power in a CMOS process.
What package does the CD74HC154MG4 use?
The CD74HC154MG4 is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package, designated by JESD-30 code R-PDSO-G24. This surface-mount package with 1.27mm pin pitch is widely supported by PCB design tools and is suitable for high-volume automated assembly.
Is the CD74HC154MG4 RoHS compliant?
Yes, the CD74HC154MG4 is RoHS compliant and lead-free, as indicated by Pbfree Code: Yes and JESD-609 Code e4. The plastic/epoxy SOIC-24 package uses environmentally compliant materials meeting current RoHS and REACH directives for electronic components.
