1 / 10 page © Semiconductor Components Industries, LLC, 2006 December, 2006 − Rev. 8 1 Publication Order Number: MC74AC574/D MC74AC574, MC74ACT574 Octal D Flip−Flop with 3−State Outputs 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. Features • 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 Figure 1.
