74ALVT16823DL,518

Overview

The 74ALVT16823DL,518 is a 20-bit bus-interface D-type flip-flop manufactured by Nexperia USA Inc. under the 74ALVT logic series. It operates at supply voltages of 2.5 V or 3.3 V and features positive-edge triggering with three-state outputs. The device integrates two independent 10-bit registers, each coupled to a dedicated output buffer controlled by separate clock (nCP) and output enable (nOE) signals. Packaged in a 56-pin SSOP (SOT371-1), it supports an operating temperature range from -40 °C to +85 °C. Key electrical parameters include a maximum propagation delay of 4.4 ns at 3.3 V with 50 pF load, low static current consumption, and high output drive capability suitable for bus interface applications.

Feature Summary

• Integrates two independent 10-bit registers with dedicated control gates for clock and output enable
• Provides positive-edge triggered data latching with three-state output buffers
• Designed for 2.5 V and 3.3 V operation with I/O compatibility to 5 V systems
• Combines high-speed performance with low static and dynamic power dissipation

Applications

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or official manufacturer channels. Confirm package marking and lot codes match the 74ALVT16823DL,518 specification. Check datasheet revisions for any design changes affecting pinout or electrical characteristics. Ensure handling procedures comply with moisture sensitivity level requirements during assembly.

Selection Notes

Select this component when designing systems requiring 20-bit parallel data storage with independent register control. Consider the 56-pin SSOP package constraints for PCB layout and thermal management. Evaluate the 4.4 ns propagation delay against system timing requirements. Verify that the 2.5 V/3.3 V supply range aligns with the target application voltage nodes and noise immunity needs.
