SN74LVC821ADBR

Flip Flops Overview

The SN74LVC821ADBR is a 10-bit D-type flip-flop from the Texas Instruments LVC series, housed in a 24-SSOP 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 positive-edge triggering, non-inverting outputs, and three-state output capability. It supports CMOS and TTL input types, offers 24mA high and low level output currents, and functions within an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides ten independent D-type flip-flops with positive-edge clock triggering for synchronous data storage.
• Features three-state outputs that allow direct connection to wired-OR buses or other active drivers.
• Supports both CMOS and TTL logic input levels for compatibility across mixed-voltage interfaces.

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Bus interface circuits requiring tri-state control
• Synchronous state machines and register files

Flip Flops Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist. Confirm package integrity and pin alignment against the 24-SSOP specification. Ensure supply voltage limits are strictly observed during operation. Check RoHS compliance status if environmental regulations apply to the assembly process.

Flip Flops Selection Notes

Select this component when ten parallel bits of storage are required in a compact surface-mount footprint. The LVC series ensures low power consumption suitable for battery-operated devices. Verify that the 7.3ns delay meets timing requirements for the target clock frequency of up to 150MHz.

Flip Flops Part Context

This part belongs to the SN74LVC821A family of 10-bit D-type flip-flops. It shares functional characteristics with other variants like the SN74LVC821ADW but differs in packaging. The LVC series is designed for low-voltage applications ranging from 1.65V to 3.6V.

Flip Flops Replacement Considerations

SN74LVC821ADBRE4 is a verified equivalent variant within the same product line offering identical electrical specifications and functionality.
