SN74ABT821ADWG4

Flip Flops Overview

The SN74ABT821ADWG4 is a bus interface flip-flop from Texas Instruments' ABT logic series. It features ten non-inverting D-type inputs and three-state outputs in an SOIC-24 package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a propagation delay of 6.2 ns. Output drive capabilities include -32 mA for high-level and 64 mA for low-level currents. It supports TTL input levels and functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates ten D-type flip-flops into a single bus interface configuration
• Provides high-drive three-state outputs for efficient data transfer
• Compatible with standard TTL input logic levels

Flip Flops Applications

• High-speed parallel data bus interfacing
• System register implementations
• Data buffering between microprocessors and peripheral devices

Flip Flops Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm environmental compliance status and exact pinout compatibility. Ensure the SOIC-24 package dimensions match the target PCB footprint requirements before finalizing component selection for production.

Flip Flops Selection Notes

Select this component when a wide data path requires synchronous storage with direct bus connectivity. The ABT technology offers superior speed compared to standard CMOS families while maintaining robust output drive strength suitable for driving multiple loads on a shared data bus architecture.

Flip Flops Part Context

This part belongs to the SN74ABT821A family of bus interface flip-flops. It serves as a specialized logic solution for managing large data words in digital systems, bridging the gap between high-speed processing units and memory or I/O subsystems requiring registered data paths.

Flip Flops Replacement Considerations

The SN74ABT821ADWR is a reel-packaged variant of the same logical function and specifications. Verify that the packaging format change does not impact automated assembly processes.
