MC74ACT574ML1

Flip Flops Overview

The MC74ACT574ML1 is an octal D-type flip-flop from the onsemi 74ACT logic family, housed in a 20-SOEIAJ surface-mount package. It features eight non-inverting outputs with tri-state control, enabling efficient bus-oriented memory mapping and line driving. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 85 MHz. Key electrical characteristics include a propagation delay of 2 ns at 5 V with 50 pF load, and output drive capabilities of -24 mA (high) and 24 mA (low). It functions reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered configuration with tri-state output control for bus isolation
• High-speed performance supporting 85 MHz clock frequencies and 2 ns propagation delay
• Robust output drive capability with ±24 mA current sourcing and sinking

Flip Flops Applications

• Bus-oriented memory register implementations
• Line drivers for high-speed data transmission
• Parallel-to-serial conversion circuits
• Clocked data storage in digital systems

Flip Flops Procurement Notes

Verify the specific suffix ML1 against official onsemi documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 20-SOEIAJ form factor. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when high-speed octal latching with tri-state outputs is required in a compact surface-mount footprint. Compare against standard 74HC or 74HCT variants if lower speed or different voltage levels are acceptable. Consider the 2 ns propagation delay and 85 MHz limit for timing-critical designs. Evaluate thermal management needs given the SOEIAJ package size and operating temperature range.

Flip Flops Part Context

This part belongs to the 74ACT series, which combines CMOS low power consumption with TTL-compatible speeds. The MC74ACT574ML1 specifically provides eight bits of storage with three-state outputs, making it suitable for multiplexed data buses. It is distinct from the PC (DIP) and DWG (SOIC) packages by using the smaller SOEIAJ format.

Flip Flops Replacement Considerations

MC74ACT574DWG offers identical electrical specifications in a SOIC-20 package. MC74ACT574PC_Q provides the same functionality in a PDIP-20 through-hole package. Verify pinout compatibility and mechanical dimensions before substituting.
