74ALVT16823DGGY

Overview

The 74ALVT16823DGGY is a dual 9-bit D-type flip-flop with 3-state outputs manufactured by Nexperia. It belongs to the ALVCH logic family and operates within a supply voltage range of 2.3 V to 3.6 V. The device features Schmitt-trigger inputs for noise tolerance and includes an I_OFF circuit for partial power-down protection. It is housed in a 56-pin TSSOP package (SOT364) and supports surface-mount installation.

Feature Summary

• Dual 9-bit D-type flip-flops with 3-state outputs
• Schmitt-trigger inputs for slow signal processing
• I_OFF circuitry prevents backflow during partial power-down
• Automotive qualification compliant

Applications

• Automotive data bus systems
• Industrial control interfaces
• High-density memory buffering

Procurement Notes

This component is designated as End-of-Life (EOL). Manufacturers have issued discontinuation notifications, indicating that production will cease. Availability is restricted to existing stock or third-party distributors. Verify current lifecycle status and lead times carefully before finalizing design-in decisions due to potential obsolescence risks.

Selection Notes

Select this part only if legacy compatibility with the 74ALVT16823 specification is required. Consider alternative ALVCH series devices with active lifecycles for new designs. Ensure the 56-TSSOP footprint matches the PCB layout constraints. Verify that the 2.3 V to 3.6 V operating range aligns with the system power rails.

Part Context

Part of the Nexperia 74ALVCH series, designed for low-voltage applications requiring high speed and low power consumption. The ALVCH family combines advanced CMOS technology with Schmitt-trigger inputs, making it suitable for noisy environments. This specific variant integrates dual 9-bit registers in a compact surface-mount package.

Replacement Considerations

Check Nexperia's official substitution guide for equivalent ALVCH series parts. Verify pinout compatibility and electrical specifications against alternatives like the 74ALVT16823DL. Confirm that replacement components maintain the same automotive qualification standards if used in vehicle applications.
