MC74AC377N

Flip Flops Overview

The MC74AC377N is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features eight non-inverting outputs and operates within a supply voltage range of 2V to 6V. The device utilizes positive-edge triggering for data capture. Key electrical parameters include a maximum propagation delay of 10ns at 5V with 50pF load, and output drive currents of ±24mA. Static current consumption is specified at 8µA. The component supports a clock frequency of up to 140MHz and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight independent storage elements
• Positive-edge triggered operation for precise timing control
• Non-inverting output configuration maintaining input signal polarity
• CMOS technology enabling low static power consumption

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital data buses
• Shift register construction in sequential logic systems
• Memory interface data holding applications

Flip Flops Procurement Notes

Verify that the ordering suffix 'N' corresponds to the 20-PDIP package variant rather than surface-mount options like TSSOP or SOIC. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the 2V to 6V operational voltage limits and thermal requirements for the intended application environment.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with through-hole mounting capability is required. The 74AC series offers higher speed performance compared to standard 74LS equivalents while maintaining CMOS power efficiency. Consider the 20-PDIP package form factor for prototyping or legacy board designs requiring axial insertion compatibility.

Flip Flops Part Context

This part belongs to the MC74AC377 family of octal D-type flip-flops produced by onsemi. It shares functional characteristics with other members of the 74AC logic family but differs in packaging and specific suffix designations. The MC74AC377N specifically denotes the dual in-line package version, distinguishing it from surface-mount variants such as the MC74AC377DTG or MC74AC377DWG.

Flip Flops Replacement Considerations

Direct substitutes include other 74AC377 variants with compatible packages. Verify pinout compatibility when replacing with different package types. Cross-reference with MC74ACT377 for 5V-only applications if AC voltage flexibility is not required.
