74LCXH16244MEA

Overview

The onsemi 74LCXH16244MEA is a low-voltage 16-bit buffer and line driver featuring bus-hold functionality. It operates within a voltage range of 2.0V to 3.6V and utilizes a 48-lead Small Shrink Outline Package (MS48A). The device provides non-inverting logic with five-volt tolerant inputs and outputs, ensuring compatibility in mixed-voltage systems.

Feature Summary

• Integrates bus-hold circuitry to maintain stable signal states during idle periods
• Supports five-volt tolerant input and output interfaces for system interoperability
• Designed for high-speed digital signal buffering and bus driving applications

Applications

• Digital signal buffering in consumer electronics
• Bus driving in industrial control systems
• Memory interface stabilization in computing hardware

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific MS48A package marking and date codes against official documentation. Ensure compliance with RoHS standards as specified in the product datasheet before integration into final assemblies.

Selection Notes

Select this component for designs requiring 16-bit parallel data handling with bus-hold capabilities. It is suitable for low-voltage logic families operating between 2.0V and 3.6V. Consider the 48-lead SSOP footprint for PCB layout constraints and thermal management requirements in dense electronic assemblies.

Part Context

This part belongs to the 74LCXH series, which extends the standard 74LCX family with enhanced bus-hold features. It serves as a specialized solution for maintaining signal integrity in high-density digital buses where noise immunity and state retention are critical design parameters.

Replacement Considerations

The SN74LVCH16244ADL from Texas Instruments is listed as a direct substitute. Verify pinout compatibility and electrical specifications before implementation.
