74LCXR2245MTCX

Overview

The Fairchild Semiconductor 74LCXR2245MTCX is a low-voltage CMOS octal bus transceiver featuring 5V tolerant inputs and outputs. It operates within a supply voltage range of 1.65V to 3.6V and utilizes a 20-pin TSSOP package. The device provides bidirectional data transmission with three-state outputs, enabling effective bus line management in embedded systems.

Feature Summary

• Provides bidirectional data transfer between two buses
• Features 5V tolerant I/O for mixed-voltage system compatibility
• Supports three-state output control for efficient bus sharing

Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'MTCX' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the Fairchild part number with current onsemi documentation, as corporate restructuring may affect legacy part availability and documentation hosting.

Selection Notes

Select this component when designing systems requiring interface between 1.8V or 3.3V logic domains and 5V peripherals. The 5V tolerance eliminates the need for level shifters, simplifying circuit design. Consider the TSSOP package dimensions for PCB layout constraints and verify that the operating temperature range aligns with environmental requirements.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The LCX family is designed for high-speed applications with low power consumption. This specific model functions as an octal transceiver, differing from standard logic gates by providing directional control and bus isolation capabilities essential for complex digital interfaces.

Replacement Considerations

The 74LCXR2245MTC is the non-reel version of this component. Verify pinout compatibility before substitution. Consult onsemi documentation for any updated electrical specifications or recommended operating conditions associated with the rebranded product line.
