74LCX652MTCX

Overview

The 74LCX652MTCX is a registered bus transceiver from the onsemi 74LCX logic family, housed in a 24-pin TSSOP package. It operates within a supply voltage range of 2V to 3.6V and supports bidirectional data transmission across an 8-bit width. The device features D-type flip-flops that allow data to be clocked directly from input buses or internal registers. It provides 5V tolerant inputs and outputs, enabling seamless interfacing between low-voltage systems and 5V signal environments while maintaining low power consumption.

Feature Summary

• Integrates D-type flip-flops for multiplexed data transmission from input buses or internal registers
• Provides 5V tolerant inputs and outputs for safe interfacing with 5V signal environments
• Features independent Output Enable controls (OEAB, OEBA) for managing transceiver directionality

Applications

• Low voltage (2.5V or 3.3V) system bus interfaces
• Bidirectional data buffering between different voltage domains
• Registered data storage and transfer in communication equipment

Procurement Notes

Verify the specific manufacturer source, as the 74LCX652 series was originally developed by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the component meets current RoHS compliance standards and check for any relevant Product Change Notifications (PCN) regarding packaging or manufacturing site updates. Ensure the datasheet version aligns with the required electrical specifications for your design.

Selection Notes

Select this component when a registered bidirectional interface is required between 3.3V or 2.5V logic and 5V tolerant peripherals. The inclusion of D-type flip-flops allows for data latching, which is essential for synchronous bus operations. Consider the 24-pin TSSOP package constraints and ensure the thermal performance is adequate for the intended operating temperature range of -40°C to +85°C.

Part Context

The 74LCX652 belongs to the LCX/LVC/Z series of low-voltage CMOS logic devices. This series is characterized by high speed and low power consumption, designed specifically for applications requiring operation at 2.5V or 3.3V. The registered bus transceiver variant adds memory functionality to standard bus drivers, facilitating complex data handling in modern electronic systems.

Replacement Considerations

The 74LCX652CW is a documented equivalent part number for this device. Verify pinout compatibility and electrical characteristics against the original datasheet before substitution.
