74ALVCH16823DL,512

Overview

The 74ALVCH16823DL,512 is a high-performance BiCMOS device featuring two 10-bit D-type flip-flops with positive-edge triggering and 3-state outputs. Designed for VCC operation at 2.5 V or 3.3 V, it provides I/O compatibility to 5 V. The device incorporates 30 Ohm termination resistors on the data inputs to minimize signal reflections. It operates within a supply voltage range of 2.3 V to 3.6 V and supports a maximum clock frequency of 350 MHz. The package is a 56-pin SSOP (SOT371-1), suitable for surface-mount applications.

Feature Summary

• Integrates 30 Ohm series termination resistors on all data inputs to reduce signal reflections in bus-interface applications.
• Provides high-speed performance with a maximum clock frequency of 350 MHz and low propagation delay.
• Features 3-state outputs controlled independently by output enable gates for efficient bus driving.
• Ensures 5 V tolerant I/O capability, allowing direct interfacing with 5 V logic systems.

Applications

• High-speed parallel data acquisition systems requiring precise timing control.
• Bus interface circuits connecting 3.3 V processors to 5 V peripheral devices.
• Memory buffer stages in communication equipment operating at 2.5 V or 3.3 V.
• Clock distribution networks where signal integrity is maintained via integrated termination.

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm RoHS compliance status and check for Product Change Notifications (PCN) regarding label or packaging updates. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering. Validate that the specific suffix matches the required pinout and electrical specifications for your design.

Selection Notes

Select this component when designing systems requiring 10-bit wide registers with integrated input termination for signal integrity. It is appropriate for applications needing 5 V tolerance on both inputs and outputs while operating from a 3.3 V or 2.5 V core supply. Consider the 56-pin SSOP package constraints for PCB layout and thermal management during selection.

Part Context

This part belongs to the 74ALVCH family of advanced low-voltage CMOS logic devices. It complements other bus-interface components like the 74ALVT162821 but distinguishes itself with integrated 30 Ohm termination resistors. The ALVCH series is optimized for high-speed, low-power applications in portable and battery-operated electronics.

Replacement Considerations

Public confirmed substitute: SN74ALVCH16823DL (Texas Instruments). Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any functional differences in termination resistor values or output drive strength between manufacturers.
