SN74LVC821ADBRG4

Flip Flops Overview

The SN74LVC821ADBRG4 is a 10-bit D-type flip-flop from Texas Instruments' LVC logic series. It features positive-edge triggering and non-inverting outputs with three-state capability. The device operates within a supply voltage range of 1.65 V to 3.6 V. It supports CMOS and TTL input types and provides output drive currents of ±24 mA. The maximum propagation delay is specified at 7.3 ns under standard test conditions (3.3 V, 50 pF load). The component is housed in a 24-SSOP package and is designed for surface-mount installation.

Flip Flops Feature Summary

• Integrates ten independent D-type flip-flops into a single bus interface unit
• Provides high-drive three-state outputs for efficient bus line driving
• Supports direct interface with both CMOS and TTL logic families

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Bus interface circuits requiring wide data word handling
• High-speed timing and synchronization applications

Flip Flops Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the package variant matches the SSOP-24 footprint requirements for your PCB layout. Ensure the operating voltage range aligns with your system's power supply specifications before integration.

Flip Flops Selection Notes

Select this component when a wide parallel data path requires storage without external latch overhead. The three-state outputs facilitate connection to shared buses. Verify that the 7.3 ns propagation delay meets the timing constraints of your target clock frequency. Consider the thermal characteristics of the SSOP package for your enclosure design.

Flip Flops Part Context

This part belongs to the SN74LVC821A family of 10-bit D-type flip-flops. It is functionally equivalent to other variants in the series but differs in packaging and environmental compliance markings. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing. It serves as a core memory element for parallel data retention in logic circuits.

Flip Flops Replacement Considerations

SN74LVC821ADBR is a compatible alternative within the same series. SN74LVC821ADBRE4 is another verified substitute option. Always verify pinout compatibility and electrical specifications before substitution.
