HD74HC573 - Octal Transparent Latches

Download the HD74HC573 datasheet PDF. This datasheet also covers the HD74HC563 variant, as both devices belong to the same octal transparent latches family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • High Speed Operation: tpd (Data to Q, Q) = 11 ns typ (CL = 50 pF).
  • High Output Current: Fanout of 15 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • Low Input Current: 1 µA max.
  • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
  • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC563P HD74HC573P DILP-20 pin PRDP0020AC-B (DP-20NEV) P HD74HC563FPEL SOP-20 pin (JEI.

HD74HC563, HD74HC573 Octal Transparent Latches (with 3-state outputs) REJ03D0629-0200 (Previous ADE-205-509) Rev.2.00 Mar 30, 2006 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.
