74ALVT162821DGGY

Overview

The Nexperia 74ALVT162821DGGY is a high-performance BiCMOS bus-interface D-type flip-flop designed for 2.5 V or 3.3 V operation with I/O compatibility to 5 V. It features two 10-bit edge-triggered registers coupled to 3-state output buffers, controlled independently by clock and output enable gates. The device includes integrated 30 Ω termination resistors to minimize signal reflections. Packaged in a TSSOP-56 surface-mount format, it combines low static and dynamic power dissipation with high speed and high output drive capabilities suitable for demanding digital interfaces.

Feature Summary

• Integrates 30 Ω termination resistors within the package to enhance signal integrity on high-speed buses.
• Provides independent control of register sections via separate clock and output enable inputs.
• Ensures 5 V tolerant I/O compatibility while operating at lower 2.5 V or 3.3 V supply voltages.

Applications

• High-speed parallel data bus interfacing
• Memory interface circuits requiring level translation
• Digital systems with mixed voltage domains

Procurement Notes

Verify component authenticity through authorized distributors due to lifecycle status. Confirm that the specific suffix matches the required termination resistor configuration. Check for moisture sensitivity handling requirements during storage and assembly. Ensure design-in documentation aligns with current manufacturing standards before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring precise timing control for 20-bit wide data paths. The integrated termination resistors reduce external component count and PCB space. Consider the TSSOP-56 package constraints for thermal management and trace routing in dense layouts.

Part Context

This part belongs to the ALVT logic family, optimized for low-voltage applications with fast switching speeds. It serves as a specialized buffer and line driver solution for complex digital architectures. The device complements other Nexperia logic products by offering integrated termination features not found in standard flip-flops.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if generic ALVT series equivalents meet the specific 30 Ω termination requirement before considering alternatives.
