MC74AC377M

Flip Flops Overview

The MC74AC377M is an octal D-type flip-flop from the onsemi 74AC logic series, housed in a 20-pin PDSO package. It features eight edge-triggered D inputs and corresponding Q outputs with a common buffered clock input. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation. It exhibits a propagation delay of 13 ns and provides output drive currents of ±24 mA. The component functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight positive edge-triggered D-type flip-flops with individual data inputs and non-inverting outputs
• Includes a common buffered clock input for synchronized data loading across all channels
• Features high-current CMOS outputs capable of driving loads directly

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• General-purpose storage elements in microprocessor interfaces

Flip Flops Procurement Notes

Verify RoHS compliance status carefully, as sources indicate potential non-compliance for this specific suffix variant. Confirm package authenticity against the 20-pin PDSO specification. Cross-reference datasheet revisions to ensure functional equivalence with current production models. Validate manufacturer origin through authorized distribution channels to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with clock enable functionality is required in a surface-mount configuration. Ensure the application voltage remains within the 2V to 6V operational window. Consider the 13 ns propagation delay for timing-critical designs. Verify that the 20-pin PDSO footprint matches the PCB layout requirements before finalizing the design.

Flip Flops Part Context

This part belongs to the MC74AC377 family of octal D flip-flops manufactured by onsemi. It shares architectural similarities with other members like the MC74AC377DTG but differs in packaging and potentially compliance specifications. The AC series offers higher speed performance compared to standard 74LS counterparts while maintaining CMOS power efficiency.

Flip Flops Replacement Considerations

MC74AC377DTG: Octal D Flip-Flop in TSSOP-20 package; verify pinout compatibility. MC74AC377DWR2G: Octal D Flip-Flop in SOIC-20 package; check lead form differences.
