General Description

The MC74AC564/74ACT564 consists of eight edgetriggered flip-flops with individual D-type inputs and 3-state complementary outputs.

The buffered clock and buffered Output Enable are common to all flip-flops.

The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH Clock (CP) transition.

Overview

Octal D-Type Latch with 3-State Outputs The MC74AC564/74ACT564 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 MC74AC564/74ACT564 device is functionally identical to the MC74AC574/74ACT574, but with inverted outputs.
