CD74HC4515EN

Signal Switches, Multiplexers, Decoders Overview

The CD74HC4515EN is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 4-to-16-line decoder or demultiplexer. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. The component utilizes a 24-pin Plastic Dual In-Line Package (PDIP) for through-hole mounting. As part of the HC series, it provides standard decoding capabilities with inverted outputs suitable for general digital logic applications.

Signal Switches, Multiplexers, Decoders FAQ

What is the output polarity of the CD74HC4515EN?

The outputs are inverted, meaning the selected line goes low while others remain high.

Does the CD74HC4515EN support bidirectional data flow?

No, it functions strictly as a decoder or demultiplexer with unidirectional data flow from inputs to outputs.
