74ALVT162821DGG:11

Overview

The Nexperia 74ALVT162821DGG:11 is a high-performance BiCMOS device 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 device includes positive-edge trigger functionality and integrated 30 Ohm termination resistors. It operates within a supply voltage range of 2.3 V to 3.6 V, with a maximum propagation delay of 3 ns at 3.3 V. The component supports single-ended inputs and non-inverting polarity, housed in a TSSOP-56 package.

Feature Summary

• Integrates two independent 10-bit D-type flip-flop registers with positive-edge triggering for precise data synchronization.
• Features built-in 30 Ohm termination resistors to enhance signal integrity on high-speed bus interfaces.
• Provides 3-state outputs controlled by dedicated clock and output enable gates for flexible bus management.

Applications

• High-speed parallel data bus interfacing in digital systems
• Memory interface circuits requiring low power dissipation
• Data acquisition systems utilizing 2.5 V or 3.3 V logic levels

Procurement Notes

Verify the specific ordering suffix ':11' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status as this series may be subject to lifecycle changes or obsolescence notices from Nexperia.

Selection Notes

Select this component when designing systems requiring 20-bit wide data paths with integrated termination. It is suitable for applications needing 3.3 V or 2.5 V operation with 5 V tolerant I/O. Consider the TSSOP-56 package constraints and thermal performance relative to your PCB layout requirements.

Part Context

This part belongs to the Nexperia ALVT family, which utilizes Advanced Low-Voltage BiCMOS Technology. This technology combines low static and dynamic power dissipation with high speed and high output drive capabilities. The family is optimized for 2.5 V and 3.3 V applications, offering improved performance over standard CMOS logic families.

Replacement Considerations

The 74ALVT162821DL,512 is a documented variant within the same functional family. Verify pinout compatibility and electrical parameters before substitution. Check for differences in packaging (TSSOP vs SSOP) and termination resistor integration if replacing with other 74ALVT162821 variants.
