74ALVT162821DL,512

Overview

The 74ALVT162821DL,512 is a high-performance BiCMOS device designed for 2.5 V or 3.3 V operation with I/O compatibility to 5 V. It features two independent 10-bit edge-triggered registers coupled to 3-state output buffers. The component operates within a supply voltage range of 2.3 V to 2.7 V and 3 V to 3.6 V. It utilizes a 56-pin SSOP package (SOT371-1) and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates two independent 10-bit D-type flip-flops with positive-edge triggering
• Provides 3-state output buffers for bus interface applications
• Ensures low static and dynamic power dissipation combined with high-speed performance

Applications

• High-speed data bus interfaces
• Parallel data transmission systems
• Memory buffer circuits

Procurement Notes

Verify the current lifecycle status before design implementation, as this component may be classified as obsolete or not recommended for new designs. Confirm availability through authorized Nexperia distributors, as standard stock levels may be limited. Ensure that the 56-pin SSOP package dimensions align with the target PCB footprint requirements.

Selection Notes

Select this component when designing systems requiring 20-bit parallel data latching at 2.5 V or 3.3 V logic levels. It is suitable for applications needing 5 V tolerant outputs. Consider alternative families if higher bit counts or different trigger mechanisms are required. Verify that the 3-state control signals match the system's clock and enable architecture.

Part Context

This part belongs to the Nexperia 74ALVT logic family, which is optimized for 2.5 V and 3.3 V applications. The ALVT series combines BiCMOS technology for high speed with CMOS low power characteristics. The 74ALVT162821 specifically addresses the need for wide-bus data storage in high-performance digital systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ALVT family. Verify if newer revisions of the 74ALVT162821 offer updated packaging or longevity guarantees. Cross-reference with other manufacturers' 20-bit register equivalents if Nexperia supply is constrained.
