MC74ACT574N

Flip Flops Overview

The MC74ACT574N is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features eight non-inverting D-type edge-triggered flip-flops with three-state outputs in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 100 MHz. Propagation delay is specified at 11 ns, with output drive capabilities of 24 mA for both high and low states. It functions reliably across an industrial temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered storage elements within a single integrated circuit.
• Three-state outputs enable direct bus driving connections without requiring additional interface hardware.
• Non-inverting polarity ensures data output matches input state upon clock activation.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in microprocessor systems
• Buffering digital signals for bus isolation

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm RoHS compliance requirements against specific project standards as historical documentation indicates potential variations. Validate pinout compatibility with existing PCB footprints before integration. Request updated datasheets directly from onsemi to ensure accurate electrical specifications are available for final design validation.

Flip Flops Selection Notes

Select this component when designing systems requiring parallel data latching with high-speed performance characteristics. The ACT series offers superior switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Verify that the 20-pin DIP package aligns with the target manufacturing process constraints.

Flip Flops Part Context

This part belongs to the widely adopted 74ACT family of logic integrated circuits, known for combining CMOS low power consumption with TTL-compatible speed. The MC74ACT574 specifically addresses applications needing multiple synchronized data storage points. Its octal architecture simplifies board layout by consolidating eight flip-flops into one package, reducing component count and interconnect complexity in digital designs.

Flip Flops Replacement Considerations

SN74ACT574N (Texas Instruments) is a confirmed equivalent substitute offering identical logical functionality and pinout compatibility for direct replacement in existing designs.
