SN74LVC821ADWR

Flip Flops Overview

The SN74LVC821ADWR is a 10-bit bus interface flip-flop from the LVC logic series, manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 1.65 V to 3.6 V. The device utilizes an SOIC-24 surface-mount package and supports TTL or CMOS inputs. Key electrical specifications include a maximum propagation delay of 8.5 ns at 2.7 V and output drive currents of ±24 mA. It functions as a non-inverting D-type flip-flop with rising-edge triggering, designed for high-speed data storage applications in industrial temperature ranges.

Flip Flops Feature Summary

• Provides ten-bit parallel data storage capability via a single integrated circuit
• Features three-state outputs to facilitate efficient bus system interfacing
• Supports low-voltage operation suitable for modern portable electronic designs

Flip Flops Applications

• High-speed data storage in digital communication systems
• Bus interface modules requiring multi-bit latching
• Portable consumer electronics utilizing low-power logic families

Flip Flops Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required RoHS compliance standards for your target market. Confirm that the SOIC-24 package dimensions align with your PCB footprint requirements before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring ten-bit parallel data retention with low power consumption. The LVC series offers improved speed compared to older standard logic families while maintaining compatibility with 3.3 V and lower voltage domains. Consider the propagation delay specifications relative to your system clock speeds to ensure timing margins are sufficient for reliable operation.

Flip Flops Part Context

This part belongs to the SN74LVC821A family of bus interface flip-flops. It serves as a digital storage element within larger logic circuits, often used to buffer or latch data lines. The device is distinct from latches like the SN74LVC373 due to its edge-triggered nature rather than level-sensitive operation.

Flip Flops Replacement Considerations

The SN74LVC821ADWG4 is a verified equivalent variant offered by the same manufacturer. Verify pin-to-pin compatibility and identical electrical parameters before substitution.
