SN74ACT564 - Octal D-Type Edge-Triggered Flip-Flops

General Description

The ’ACT564 devices are octal D-type edge-triggered flip-flops that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads.

Key Features

  • Operation of 4.5V to 5.5V VCC.
  • Inputs accept voltages to 5.5V.
  • Max tpd of 8.5ns at 5V.
  • Inputs are TTL-voltage compatible.
  • 3-state inverted outputs drive bus lines directly.
  • Flow-through architecture to optimize PCB layout.
  • Full parallel access for loading 2.
