MM74HC4514

4-to-16 Line Decoder with Latch

General Description

Features

The MM74HC4514 utilizes advanced silicon-gate CMOS

technology, which is well suited to memory address decod-

ing or data routing application. It possesses high noise

immunity and low power dissipation usually associated with

CMOS circuitry, yet speeds comparable to low power

Schottky TTL circuits. It can drive up to 10 LS-TTL loads.

■ Typical propagation delay: 18 ns

■ Low quiescent power: 80 µA maximum (74HC Series)

■ Low input current: 1 µA maximum

■ Fanout of 10 LS-TTL loads (74HC Series)

The MM74HC4514 contain a 4-to-16 line decoder and a 4-

bit latch. The latch can store the data on the select inputs,

thus allowing a selected output to remain HIGH even

though the select data has changed. When the LATCH

ENABLE input to the latches is HIGH the outputs will

change with the inputs. When LATCH ENABLE goes LOW

the data on the select inputs is stored in the latches. The

four select inputs determine which output will go HIGH pro-

vided the INHIBIT input is LOW. If the INHIBIT input is

HIGH all outputs are held LOW thus disabling the decoder.

The MM74HC4514 is functionally and pinout equivalent to

the CD4514BC and the MC1451BC. All inputs are pro-

tected against damage due to static discharge diodes from

V_CCand ground.
