SN74LVC821APWR

Flip Flops Overview

The SN74LVC821APWR is a 10-bit D-type flip-flop from the Texas Instruments LVC series, housed in a 24-TSSOP package. It operates on a supply voltage range of 1.65V to 3.6V with a maximum propagation delay of 7.3ns at 3.3V and 50pF load. The device features non-inverting tri-state outputs capable of sourcing and sinking 24mA. It supports CMOS and TTL input levels, includes an active-low asynchronous clear function, and operates within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates ten positive-edge-triggered D-type flip-flops with independent clock inputs
• Provides non-inverting tri-state outputs for bus-oriented memory word storage
• Includes an asynchronous clear input to reset all flip-flops simultaneously

Flip Flops Applications

• Bus-oriented memory word storage applications
• Registering data in high-speed digital systems
• Parallel-to-serial conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-24 tape and reel packaging configuration. Confirm that the operating voltage requirements align with the 1.65V to 3.6V specification before integration. Ensure design compatibility with the asynchronous clear functionality and tri-state output characteristics defined in the official datasheet.

Flip Flops Selection Notes

Select this component when a 10-bit parallel register with tri-state outputs is required. The LVC series ensures low power consumption and compatibility with 3.3V logic families. Consider the 24-TSSOP package dimensions and thermal performance for PCB layout constraints. Verify signal integrity requirements against the specified propagation delay metrics.
