74ALVT162821DGG512

Overview

The 74ALVT162821DGG512 is a high-performance BiCMOS device from the ALVT family, designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility to 5 V. It features two 10-bit, edge-triggered registers coupled to 3-state output buffers. The component includes 30 Ohm termination resistors and operates within a temperature range of -40 °C to +85 °C. It is housed in a 56-pin SSOP package.

Feature Summary

• Combines low static and dynamic power dissipation with high speed and high output drive capabilities.
• Features two independent 10-bit registers controlled by separate clock and output enable gates.
• Integrates 30 Ohm termination resistors for signal integrity in bus-interface applications.

Applications

• High-speed data bus interfaces requiring 2.5 V or 3.3 V operation
• Systems needing I/O compatibility between 5 V and lower voltage logic levels
• Applications demanding low power consumption with high output drive strength

Procurement Notes

Verify the specific suffix 'DGG512' against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the source document explicitly lists this exact part number variant, as generic datasheets may cover multiple packaging options. Confirm RoHS compliance status directly from the manufacturer's certification for this specific revision.

Selection Notes

Select this component when designing systems that require 20-bit wide data paths operating at 2.5 V or 3.3 V. It is suitable for applications necessitating 5 V tolerant I/Os while maintaining low power profiles. Consider the 56-pin SSOP footprint constraints and the need for integrated termination resistors in high-speed signal routing designs.

Part Context

This part belongs to the 74ALVT series of advanced low-voltage TTL-compatible logic devices. It is manufactured by Nexperia (formerly NXP Semiconductors Logic division). The device serves as a bus-interface D-type flip-flop, distinct from simple transceivers or switches, providing registered storage with tri-state outputs for complex digital system architectures.

Replacement Considerations

Consult official Nexperia replacement guides for direct pin-to-pin equivalents. Generic 74ALVT162821 variants may differ in packaging or termination resistor values. Verify functional compatibility regarding clock and enable signal timing before substitution.
