Overview
The CD4514BEG4 is a CMOS integrated circuit produced by Texas Instruments, designed as a 4-bit latch and a 4-to-16 line decoder. This device is part of the CD4514B series, which includes similar components like the CD4515B. The CD4514BEG4 features a strobed input latch and inhibit control, allowing it to hold the last input data presented prior to the strobe transition from 1 to 0. It is available in various package types, including 24-pin DIP and SOIC packages.
