SN74ABT821ADWRG4

Flip Flops Overview

The SN74ABT821ADWRG4 is a bus interface flip-flop from the Texas Instruments ABT logic series. It features ten non-inverting D-type inputs and three-state outputs housed in a 24-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 6.2 ns. Output drive capabilities include -32 mA high-level and 64 mA low-level currents. It supports surface-mount installation and functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates ten D-type flip-flops into a single bus interface configuration for efficient data storage.
• Provides three-state outputs to facilitate direct connection to system buses without external drivers.
• Delivers high-speed performance with a propagation delay of 6.2 ns for rapid signal processing.

Flip Flops Applications

• High-speed parallel data buffering in communication systems
• Register stages in microprocessor-based control architectures
• Data acquisition interfaces requiring fast capture and hold capabilities

Flip Flops Procurement Notes

Verify that the ordering suffix G4 confirms RoHS compliance and manufacturing standards. Ensure the SOIC-24 package matches the PCB footprint requirements. Confirm the ABT logic family compatibility with existing system voltage levels before integration. Check datasheet specifications for thermal management needs during operation.

Flip Flops Selection Notes

Select this component when ten-bit parallel storage with bus-compatible outputs is required. The ABT series offers superior speed compared to standard TTL or CMOS alternatives. Consider the 64 mA low-level sink current for driving moderate loads directly. Evaluate the 4.5 V to 5.5 V operating window against available power rails.

Flip Flops Part Context

This part belongs to the SN74ABT821A series of bus interface flip-flops. It complements other ABT devices like the SN74ABT374A by providing higher density per package. The ABT family bridges the performance gap between older TTL technologies and modern low-voltage CMOS solutions.
