SN74LVC821PWR

Flip Flops Overview

The SN74LVC821PWR is a 10-bit D-type flip-flop from Texas Instruments' LVC series. It features 3-state outputs and accepts CMOS or TTL inputs. The device operates on a supply voltage range of 1.65 V to 3.6 V. It exhibits a propagation delay of 8.5 ns, with output drive capabilities of 24 mA for both high and low states. Packaged in a 24-pin TSSOP, it supports non-inverting logic polarity.

Flip Flops Feature Summary

• Provides ten independent D-type flip-flops within a single integrated circuit package
• Features three-state outputs to facilitate bus-oriented memory and data transfer applications
• Accepts both CMOS and TTL input signals for flexible system integration

Flip Flops Applications

• Bus-oriented memory register implementations
• Data transfer operations between digital subsystems
• Parallel-to-serial conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix PWR indicates the tape-and-reel packaging format when sourcing components. Confirm that the manufacturer is Texas Instruments to ensure compatibility with design specifications. Check current availability status as distribution channels may vary. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component for designs requiring parallel data storage with high-speed performance. The 1.65 V to 3.6 V supply range suits low-voltage digital systems. Consider the 24-pin TSSOP package for surface-mount assembly constraints. Evaluate the 8.5 ns propagation delay against system timing requirements to ensure signal integrity across the 10-bit width.

Flip Flops Part Context

This part belongs to the SN74LVC family of logic devices, designed for low-voltage CMOS operation. It serves as a fundamental building block for sequential logic circuits. The device complements other buffer and driver components within the same series, providing reliable data latching capabilities for modern digital electronics.

Flip Flops Replacement Considerations

Consider the SN74LVC821ADWG4 as an alternative package option from the same manufacturer. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same voltage and current requirements.
