74ALVCH16823DGGY

Overview

The Nexperia 74ALVCH16823DGGY is a dual 9-bit D-type flip-flop with positive-edge triggering, housed in a 56-TSSOP package. It operates within a supply voltage range of 2.3V to 2.7V and 3V to 3.6V. The device features a maximum propagation delay of 3.7ns at 3.3V with 50pF load, a clock frequency of 350 MHz, and symmetrical output drive currents of 24mA. It includes master reset functionality and tri-state outputs.

Feature Summary

• Dual 9-bit D-type flip-flops with positive-edge triggering
• Master reset functionality for synchronous initialization
• Tri-state outputs for bus-oriented applications
• High-speed operation with low propagation delay

Applications

• Parallel data storage in high-speed digital systems
• Bus interface circuits requiring tri-state control
• Synchronous logic designs with master reset requirements
• Data register applications in communication equipment

Procurement Notes

This component is officially designated as End-of-Life (EOL) by Nexperia USA Inc. and is scheduled for discontinuation. Distributors may list limited remaining stock or obsolete inventory. Verify current availability status directly with authorized suppliers before design finalization. Consider immediate transition planning to alternative components due to impending production cessation.

Selection Notes

Select this part only if the specific 56-TSSOP package and ALVCH series characteristics are required. Note that it supports two distinct voltage ranges: 2.3V-2.7V and 3V-3.6V. Ensure system design accommodates the 350 MHz clock limit and 3.7ns propagation delay. Master reset capability should be utilized for reliable power-on states. Check EOL status carefully as new production is unavailable.

Part Context

The 74ALVCH16823 belongs to Nexperia's ALVCH family of advanced low-voltage CMOS logic devices. This specific variant provides dual 9-bit flip-flop functionality in a compact surface-mount package. It is designed for high-performance applications requiring fast switching speeds and low power consumption. The device complements other ALVCH latches and registers in complex digital logic architectures.

Replacement Considerations

Direct substitute part numbers are not explicitly confirmed in the provided documentation for this specific EOL variant. Users should consult official Nexperia replacement guides or contact distributors for qualified alternatives. Generic cross-references from other manufacturers require careful verification of pinout, electrical parameters, and package dimensions.
