HD74HC563/HD74HC573

Octal Transparent Latches (with 3-state outputs)

ADE-205-509 (Z)

1st. Edition

Sep. 2000

Description

When the latch enable (LE) input is high, the Q outputs of HD74HC563 will follow the inversion of the D

inputs and the Q outputs of HD74HC573 will follow the D inputs. When the latch enable goes low, data at

the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is

applied to the output control input, all outputs go to a high impedance state, regardless of what signals are

present at the other inputs and the state of the storage elements.

Features

•

High Speed Operation: t_pd(Data to Q, Q) = 11 ns typ (C_L= 50 pF)

High Output Current: Fanout of 15 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
