GENERAL DESCRIPTION

The 74HC/HCT4514 are high-speed Si-gate CMOS devices and are pin compatible with “4514” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT4514 are 4-to-16 line decoders/demultiplexers having four binary weighted address inputs (A (LE), and an active LOW enable input (E). The 16 outputs (Q0to Q15) are mutually exclusive active HIGH. When LE is HIGH, the selected output is determined by the data on An. When LE goes LOW, the last data present at Anare stored in the latches and the outputs remain stable. When E is LOW, the selected output, determined by the contents of the latch, is HIGH. At E HIGH, all outputs are LOW. The enable input (E) does not affect the state of the latch.
When the “4514” is used as a demultiplexer, E is the data input and A0to A3are the address inputs.
