HD74HC574 - Octal D-type Flip-Flops

Download the HD74HC574 datasheet PDF. This datasheet also covers the HD74HC564 variant, as both devices belong to the same octal d-type flip-flops family and are provided as variant models within a single manufacturer datasheet.

Description

These devices are positive edge triggered flip-flops.

The difference between HD74HC564 and HD74HC574 is only that the former has inverting outputs and the latter has noninvertering outputs.

Features

  • High Speed Operation: tpd (Clock to Output) = 13 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).

HD74HC564, HD74HC574 Octal D-type Flip-Flops (with 3-state outputs) REJ03D0630-0200 (Previous ADE-205-510) Rev.2.00 Mar 30, 2006 Description These devices are positive edge triggered flip-flops. The difference between HD74HC564 and HD74HC574 is only that the former has inverting outputs and the latter has noninvertering outputs. Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q or Q outputs on positive going transitions of the clock (CK) input. When a high logic level is applied to the output control (OC) 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.
