74ALVT16821DGGS

Overview

The 74ALVT16821DGGS is a 16-bit D-type flip-flop manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.3V to 2.7V and 3V to 3.6V. The device features positive-edge triggering and includes tri-state outputs. It is housed in a 56-TSSOP package with a width of 10mm. The component supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Provides 16-bit data storage capability via dual 8-bit D-type flip-flops
• Supports high-speed clocking with positive-edge trigger functionality
• Features tri-state outputs for bus-oriented system applications

Applications

• High-density memory buffer interfaces
• Parallel data register stages in communication systems
• Bus interface circuits requiring level translation

Procurement Notes

Verify the specific suffix DGGS corresponds to the TSSOP-56 10mm body width package configuration. Confirm that the ALVT series designation aligns with the required 2.3V/2.7V and 3V/3.6V dual-voltage operation specifications for the target circuit design. Ensure compatibility with the stated industrial temperature range.

Selection Notes

Select this component when a 16-bit parallel data latch is required with tri-state output control. The ALVT series is suitable for systems needing interface between different voltage domains. Verify that the 56-pin TSSOP footprint fits the PCB layout constraints and that the positive-edge trigger timing meets the system clock requirements.

Part Context

This part belongs to the 74ALVT logic family, which combines advanced low-power CMOS technology with TTL-compatible input levels. The 74ALVT16821 specifically addresses the need for wide-width data storage in compact surface-mount packages, serving as a key building block for complex digital logic designs requiring reliable state retention.

Replacement Considerations

SN74ALVT16821DL from Texas Instruments is a documented substitute part number.
