MC74ACT377M

Flip Flops Overview

The MC74ACT377M is an octal D-type flip-flop from the 74ACT logic series, manufactured by onsemi. It features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs, along with a common buffered Clock (CP) input. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 10 ns, a high-level output current of -24 mA, and a low-level output current of 24 mA. It is housed in a 20-SOEIAJ package.

Flip Flops Feature Summary

• Contains eight edge-triggered D-type flip-flops with individual data inputs and outputs.
• Features a common buffered clock input for synchronized loading across all stages.
• Provides single-ended non-inverting outputs with standard drive capabilities.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register storage elements in digital systems
• Timing and buffering applications requiring octal data latching

Flip Flops Procurement Notes

Verify the specific package variant, as the MC74ACT377M designation may correspond to bulk packaging while other suffixes like DWR2G indicate tape-and-reel. Confirm RoHS compliance status and ensure the source document explicitly lists this exact part number as active or available, as availability can vary by region and distributor.

Flip Flops Selection Notes

Select this component when an octal register with clock enable functionality is required in a 5V CMOS environment. Ensure the design accommodates the 20-pin SOEIAJ footprint. Compare against the MC74ACT374 if tri-state outputs are needed instead of single-ended outputs, noting that both belong to the same 74ACT family.

Flip Flops Part Context

This component belongs to the MC74AC(T)377 family of octal D flip-flops. It shares functional similarities with the MC74ACT374 but differs in output configuration. The ACT series offers faster switching speeds compared to standard AC devices, suitable for higher-frequency digital logic applications operating at 5V.

Flip Flops Replacement Considerations

MC74ACT374DWG is a related onsemi part offering similar octal D-type functionality but with tri-state outputs rather than single-ended outputs. Verify pin compatibility and output drive requirements before substitution.

Flip Flops FAQ
