CD4515 4-to-16 Line Decoder with Latch DIP-24 (CD4515 DIP IC)
The CD4515 is a high-voltage CMOS integrated circuit that functions as a 4-to-16 line decoder with an internal 4-bit storage latch. It decodes a 4-bit binary input into one of sixteen mutually exclusive low-level (active-low) outputs, making it the inverting counterpart to the CD4514.
This IC is primarily used for memory address decoding, digital demultiplexing, and controlling large arrays of indicators where active-low logic is required. It is an essential component for Arduino electronics projects in India that need to expand a few microcontroller pins to manage sixteen independent output channels.
