SN74ABT16821DLRG4

Flip Flops Overview

The SN74ABT16821DLRG4 is a dual 10-bit bus interface flip-flop from Texas Instruments, housed in a 56-pin SSOP package. It features non-inverting D-type logic with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Key electrical specifications include a maximum propagation delay of 5.1 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is designed for surface-mount installation and functions within standard industrial temperature ranges.

Flip Flops Feature Summary

• Dual 10-bit bus interface architecture for efficient data handling
• Three-state outputs enable direct connection to system buses
• ABT logic series ensures fast switching speeds with low power consumption
• Non-inverting polarity maintains signal integrity across the interface

Flip Flops Applications

• High-speed data bus interfaces in computing systems
• Memory buffer applications requiring tri-state control
• Parallel data transmission lines in industrial controllers
• System interconnects needing fast propagation delays

Flip Flops Procurement Notes

Verify the exact ordering suffix matches the required package variant, as 'DLRG4' specifies the SSOP-56 tape and reel configuration. Confirm that the RoHS compliance status aligns with your manufacturing requirements. Ensure the operating temperature range meets your specific environmental constraints before finalizing the purchase order.

Flip Flops Selection Notes

Select this component when a dual 10-bit width is required rather than the full 20-bit capacity of similar ABT devices. The SSOP-56 package is suitable for space-constrained designs where TSSOP alternatives are not feasible. Consider the 5.1 ns propagation delay for timing-critical paths and verify that the 64 mA sink current capability satisfies the load requirements of the destination circuitry.

Flip Flops Part Context

This part belongs to the SN74ABT1682x family of 20-bit bus interface flip-flops. While the base model typically handles 20 bits, the SN74ABT16821 variant is configured as two independent 10-bit sections. It shares the same ABT technology and pinout structure as other members like the SN74ABT16823, differing primarily in internal bit grouping and functional partitioning.

Flip Flops Replacement Considerations

The SN74ABT16821DLR is the primary equivalent without the lead-free designation. For identical functionality in a different package, consider the SN74ABT16821DGGR in TSSOP-56 format. Verify that any substitute maintains the same 56-pin footprint and electrical characteristics to ensure compatibility.
