74ALVT16823DL,512

Overview

The 74ALVT16823DL,512 is a dual 9-bit D-type flip-flop manufactured by Nexperia USA Inc. in the ALVT logic series. It features positive-edge triggering and is housed in a 56-pin SSOP package (SOT371-1). The device operates within a supply voltage range of 2.3V to 2.7V or 3.0V to 3.6V. Key electrical specifications include a maximum propagation delay of 4.4ns at 3.3V with 50pF load, static current of 70µA, and input capacitance of 3pF. It supports standard VCC = 3.3V ±0.3V operation and includes master reset functionality.

Feature Summary

• Dual independent 9-bit D-type flip-flops with positive-edge clocking
• Supports 2.5V and 3.3V operating voltages for versatile system integration
• Includes master reset function for synchronous data control
• Non-inverting outputs with tri-state capability

Applications

• High-density memory interface circuits requiring parallel data latching
• Buffered register stages in high-speed digital signal processing systems
• Data acquisition systems utilizing 2.5V or 3.3V logic levels

Procurement Notes

This component is designated as not recommended for new designs and has reached end-of-life status. Availability is limited to existing stock from distributors; no new production is scheduled. Verify lead times carefully as inventory may be scarce. Ensure compliance with RoHS3 standards if required for specific environmental regulations. Sourcing should focus on authorized distributors holding remaining quantities.

Selection Notes

Select this part when a dual 9-bit latch is required for 2.5V/3.3V ALVT applications. Consider the 56-SSOP package constraints for PCB layout. Evaluate the 4.4ns propagation delay against system timing requirements. Since it is obsolete, assess long-term supply chain risks and consider alternative components for future projects.

Part Context

Part of the Nexperia 74ALVT family, designed for low-voltage operations. The 'DL' suffix indicates the SSOP-56 package type, while ',512' denotes tape and reel packaging. It belongs to the broader category of bus drivers and flip-flops used in complex digital logic systems requiring precise timing and voltage translation between different logic families.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the end-of-life status, direct pin-compatible alternatives from other manufacturers should be evaluated based on electrical specifications and package dimensions.
