74ALVT162821DGG112

Overview

The 74ALVT162821DGG,112 is a high-performance BiCMOS device from the ALVT logic series. It functions as a 20-bit bus-interface D-type flip-flop with positive-edge triggering and integrated 30-ohm termination resistors. The component features two independent 10-bit registers coupled to 3-state output buffers, controlled by separate clock (nCP) and output enable (nOE) gates. Designed for VCC operation at 2.5V or 3.3V, it ensures I/O compatibility with 5V systems. The device is housed in a 56-pin SSOP package.

Feature Summary

• Integrates 30-ohm termination resistors to enhance signal integrity on high-speed buses
• Provides dual independent 10-bit edge-triggered registers for flexible data handling
• Supports mixed-voltage operation with 5V tolerant I/O interfaces

Applications

• High-speed parallel data bus interfacing
• Memory buffer applications requiring precise timing control
• System-level data acquisition and storage circuits

Procurement Notes

Verify the complete ordering code, including the suffix, against official Nexperia documentation to ensure correct package and tape/reel specifications. Confirm current availability status, as this component may be subject to lifecycle changes or obsolescence notices. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and sourcing channels before procurement.

Selection Notes

Select this component when designing systems requiring 20-bit synchronous data latching with integrated termination for impedance matching. Ensure the design environment supports the specified 2.5V or 3.3V supply voltage. Verify that the 56-pin SSOP footprint aligns with the PCB layout constraints and that the thermal performance meets the operational temperature range requirements.
