MC74ACT374DW

Flip Flops Overview

The MC74ACT374DW is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features a single element with eight bits of data storage and positive-edge triggering. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 160 MHz. Key electrical parameters include a maximum propagation delay of 10ns at 5V with 50pF load, static current of 8µA, and input capacitance of 4.5pF. Outputs provide source/sink currents of 24mA each and are tri-state non-inverting. The component is housed in a 20-SOIC package (0.295" width) and functions across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering for synchronous data capture.
• Tri-state non-inverting outputs providing high drive capability of 24mA source and sink current.
• TTL-compatible inputs facilitating integration with standard TTL logic systems.
• High-speed operation supporting clock frequencies up to 160 MHz.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register file implementations in digital processing systems
• Buffering and latching applications requiring high drive strength

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate pinout compatibility with existing PCB footprints before integration. Check for available direct replacements if new production is required.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs and high output drive current are necessary. Ensure the operating voltage aligns with the 4.5V to 5.5V specification. Consider the 20-SOIC package constraints for board layout. Evaluate replacement options if long-term availability is a critical project requirement.

Flip Flops Part Context

This part belongs to the 74AC(T)374 family of octal D-type flip-flops. It shares functional similarities with other variants like MC74AC374 but differs in input threshold characteristics due to the ACT series specifications. The device is designed for general-purpose digital logic applications requiring reliable data storage and transfer.

Flip Flops Replacement Considerations

Direct substitutes include MC74ACT374DWG from onsemi. Cross-manufacturer alternatives such as CD74ACT374M and SN74ACT374DWR from Texas Instruments offer compatible functionality and pinouts.
