Datasheet

Products

Overview

The MC74AC574/74ACT574 is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition.

The MC74AC574/74ACT574 is functionally identical to the MC74AC374/ 74ACT374 except for the pinouts.

  • Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors
  • Useful as Input or Output Port for Microprocessors
  • Functionally Identical to MC74AC374/74ACT374
  • 3-State Outputs for Bus-Oriented Applications
  • Outputs Source/Sink 24 mA
  • ACT574 Has TTL Compatible Inputs
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
