74LCX16543MTD

Overview

The onsemi 74LCX16543MTD is a low-voltage 16-bit registered transceiver designed for high-speed data transfer in systems operating at 2.5V or 3.3V VCC. It features five-volt tolerant inputs and outputs, allowing direct interfacing with 5V devices without level shifting. The device contains two D-type registers to temporarily store data flowing in either direction, with independent control inputs for each byte pair. Manufactured using advanced CMOS technology, it ensures high-speed operation while maintaining low power consumption typical of CMOS circuits.

Feature Summary

• Features five-volt tolerant inputs and outputs for seamless interface with 5V signal environments
• Includes dual D-type registers to latch and store data during bidirectional transmission
• Utilizes advanced CMOS technology to achieve high-speed performance with minimal power dissipation

Applications

• Low-voltage memory bus architectures requiring voltage translation
• High-density data acquisition systems utilizing 3.3V logic
• Portable electronic devices demanding low power consumption and high speed

Procurement Notes

Verify the specific suffix 'MTD' against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve over time.

Selection Notes

Select this component when designing systems that bridge 5V legacy interfaces with modern 3.3V or 2.5V logic cores. The integrated latching capability simplifies timing constraints in asynchronous data transfers. Consider the 5V tolerance feature to eliminate external level-shifting components, thereby reducing bill of materials cost and board space.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from onsemi. The LCX family is optimized for applications requiring fast switching speeds and low static power. As a registered transceiver, it differs from non-latched variants by providing data storage capabilities essential for synchronized system operations.
