74ALVT16260DL,518

Overview

The NXP USA Inc. 74ALVT16260DL,518 is a 12-bit to 24-bit multiplexed D-type latch featuring 3-state outputs. It operates with a supply voltage range of 2.3 V to 3.6 V and supports 5 V I/O compatibility. The device includes bus hold inputs to eliminate external pull-up resistors and provides power-up reset functionality. It is available in SSOP56 (SOT371-1) and TSSOP56 packages, designed for applications requiring multiplexing or demultiplexing of address and data information.

Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Power-up reset ensures defined initial states
• Live insertion and extraction permitted
• Distributed VCC and GND pin configuration minimizes high-speed switching noise

Applications

• Multiplexing or demultiplexing of address and data information in microprocessor applications
• Bus-interface applications requiring dual data path handling
• Memory-interleaving applications

Procurement Notes

Verify the specific package variant required, as the base part number covers both SSOP56 and TSSOP56 options. Confirm that the 'DL,518' suffix corresponds to the correct reel quantity and packaging format intended for your assembly line. Ensure design reviews account for the 5 V I/O tolerance when interfacing with legacy logic families.

Selection Notes

Select this component when designing systems that require simultaneous handling of two separate 12-bit data paths onto a single 24-bit bus interface. The inclusion of internal storage latches allows for flexible data retention without external memory components. Consider the distributed power and ground pins if minimizing signal integrity issues at high switching speeds is a primary design constraint.

Part Context

This device belongs to the 74ALVT logic family, characterized by BiCMOS technology offering high speed and low power dissipation. It is specifically engineered for 2.5 V and 3.3 V operation while maintaining compatibility with 5 V systems. The multiplexed latch architecture distinguishes it from standard bus transceivers by providing dedicated control for independent data storage and selection.

Replacement Considerations

Direct replacements must match the 12-bit to 24-bit multiplexed latch functionality and 56-pin SSOP/TSSOP footprint. Verify that alternative parts support the same 5 V I/O tolerance and bus hold features to maintain circuit stability without additional external components.
