CD4514 4 Bit Latch/4-16 Line Decoder IC DIP-24 Package

The CD4514 is a CMOS 4-bit latch and 4-to-16 line decoder integrated circuit in a DIP-24 package. It accepts a 4-bit binary input and decodes it into one of 16 active-high outputs, with an internal latch to hold the input data. This IC is used for address decoding, demultiplexing, and expanding digital outputs in microcontroller and logic systems.

What is the pinout of the CD4514?

The CD4514 has 24 pins. Pins 1–4 are the 4-bit address inputs (A0–A3). Pins 5–20 are the 16 decoded outputs (Y0–Y15). Pin 21 is STROBE (latch enable), pin 22 is INHIBIT (output disable), pin 23 is VDD (positive supply), and pin 24 is VSS (ground). Refer to the datasheet for the complete pin diagram.

What is the difference between CD4514 and CD4515?

The CD4514 has active-high outputs (output goes HIGH when selected), while the CD4515 has active-low outputs (output goes LOW when selected). Both share the same pinout and latch/decoder logic.
