HD74HC564P Datasheet Octal D-type Flip-flop

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC564/HD74HC574 Octal D-type Flip-Flops (with 3-state outputs).

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

Key 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) Function Table Outputs Output Control Clock Data HD74HC564 HD74HD574 L H L H L L H L L L H X X Q0 Q0 X Z Z Q0 : level of Q before the indicated Steady-sate input conditions were.
