74LCX652MTC

Overview

The Fairchild Semiconductor 74LCX652MTC is a registered bus transceiver belonging to the LCX logic family. It integrates eight-bit D-type flip-flops with control circuitry for multiplexed data transmission from input buses or internal registers. The device supports low-voltage operation at 2.5V or 3.3V while providing compatibility with 5V signal environments through tolerant inputs and outputs. It utilizes advanced CMOS technology to ensure high-speed performance with a propagation delay of 10.5 ns. The component is housed in a 24-pin SSOP package, suitable for surface-mount applications within industrial temperature ranges.

Feature Summary

• Multiplexed transmission capability allowing direct data transfer from input buses or latched data from internal registers
• 5V tolerant inputs and outputs enabling seamless interfacing between low-voltage systems and 5V signal environments
• D-type flip-flop integration for data storage and synchronized clocked transmission

Applications

• Low voltage (2.5V/3.3V) to 5V system interface bridging
• Multiplexed data bus architectures requiring register buffering
• High-density electronic equipment utilizing surface-mount technology

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the source document matches the exact part number to avoid confusion with similar LCX series variants.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between different voltage domains. The 5V tolerance feature makes it suitable for legacy 5V interfaces connected to modern low-voltage processors. Consider the registered output structure for applications requiring stable data holding during clock transitions.
