CD4514 4-to-16 Line Decoder with Latch DIP-24 (CD4514 DIP IC)
The CD4514 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 high-level outputs, provided the inhibit input is low.
This IC is primarily used for memory address decoding, digital demultiplexing, and controlling large arrays of LEDs or relays. It is a vital component for Arduino electronics projects in India that require expanding a few microcontroller pins to control up to sixteen independent output channels.
