What are the key features of CD74HC4515EN?
- 4-to-16 line decoder/demultiplexer with built-in address latches eliminates external latch ICs, reducing BOM count in multiplexed bus designs
- HC-family CMOS logic supports 2 V to 6 V VCC operation with 50 pF load capacitance and 4 mA output sink current for direct LED or relay driving
- 24-pin PDIP through-hole package simplifies breadboard prototyping and low-volume PCB assembly for industrial control and address decoding applications
What is CD74HC4515EN used for?
The CD74HC4515EN is commonly used in memory address decoding, I/O port expansion, and display multiplexing circuits where a 4-bit address bus must select one of 16 output lines. It also suits industrial programmable logic controllers and embedded systems requiring latched address demultiplexing to drive discrete output channels or segment display grids.

Frequently Asked Questions
How many output lines does the CD74HC4515EN decode from a 4-bit input address?
The CD74HC4515EN decodes a 4-bit binary address (16 combinations) into one of 16 individual active-low output lines, with all other outputs remaining high. Built-in address latches allow the decoded output to be held stable while the address bus changes, useful in multiplexed systems with 50 pF load capacitance per output.
What supply voltage range and output drive current does the CD74HC4515EN support?
The CD74HC4515EN operates from 2 V to 6 V VCC as an HC-family CMOS device, and provides a maximum output sink current of 4 mA per output pin. This allows direct drive of small LEDs, optocouplers, or relay coils in 3.3 V and 5 V logic systems without external buffer transistors.
How do the integrated address latches in the CD74HC4515EN benefit bus-multiplexed system designs?
The integrated address latches in the CD74HC4515EN capture and hold the 4-bit input address on the latch enable edge, keeping the selected output line asserted even when the input bus transitions to a new address. This eliminates the need for a separate 74HC373 or 74HC374 latch IC, saving one package and reducing board area by approximately 1 cm2 in a 24-DIP layout.
Which package does the CD74HC4515EN use and how does it compare to SOIC alternatives for prototyping?
The CD74HC4515EN comes in a 24-pin PDIP (DIP-24) package with 2.54 mm (100 mil) pin pitch and 15.24 mm (600 mil) body width, which plugs directly into standard solderless breadboards. The SOIC-24 equivalent requires an SMT adapter for breadboard use, so the PDIP variant is preferred for prototyping and small production runs.
