MC74ACT564NG

Flip Flops Overview

The MC74ACT564NG is an octal D-type flip-flop with inverted outputs and 3-state capabilities, belonging to the onsemi 74ACT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum load capacitance of 50 pF. The device features a common Output Enable (OE) pin and stores data at the LOW-to-HIGH Clock transition. It utilizes a 20-lead Plastic Dual In-Line Package (PDIP-20). The component functions identically to the non-inverting MC74AC574 variant but provides inverted outputs for bus-oriented applications.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with inverted outputs
• Common Output Enable (OE) control for bus-oriented applications
• Data storage triggered by LOW-to-HIGH Clock transitions
• Inputs and outputs positioned on opposite sides of the package

Flip Flops Applications

• Microprocessor input or output port interfacing
• Bus-oriented digital systems requiring inverted data latching
• High-speed low-power logic circuits

Flip Flops Procurement Notes

Verify that the ordering suffix 'N' corresponds to the PDIP-20 plastic dual in-line package configuration. Confirm compliance status as the datasheet indicates this specific part number may not be RoHS compliant. Ensure the design accommodates the 4.5 V to 5.5 V operating voltage range and the specified -40 °C to +85 °C temperature limits.

Flip Flops Selection Notes

Select this component when inverted octal latching is required for 5V CMOS systems. It serves as the functional equivalent to the MC74AC574/74ACT574 series but with inverted outputs. Consider the PDIP-20 package constraints for through-hole mounting requirements and verify compatibility with standard 74ACT logic levels.

Flip Flops Part Context

This component belongs to the MC74AC564/74ACT564 high-speed, low-power octal D-type flip-flop family. It shares functional characteristics with the MC74AC574/74ACT574 devices, distinguished primarily by its inverted output polarity. The device is designed for efficient data storage and transfer in complex digital logic environments.

Flip Flops FAQ

How does the MC74ACT564NG differ from the MC74AC574?

The MC74ACT564NG provides inverted outputs, whereas the MC74AC574 provides non-inverting outputs. Both share identical internal functionality and pin configurations.

What triggers the data storage in this device?

Information presented to the D inputs is stored in the flip-flops upon the LOW-to-HIGH transition of the Clock (CP) signal.
