MC74LCX652DW

Overview

The MC74LCX652DW is a registered bus transceiver from the 74LCX logic family, manufactured by onsemi. It features eight circuits in an SSOP-24 package. The device operates with a supply voltage range of 2 V to 3.6 V and supports LV TTL or TTL input levels while providing LV CMOS output levels. It exhibits a propagation delay of 9.5 ns and delivers a low-level output current of 24 mA with a high-level output current of -24 mA. The outputs are three-state.

Feature Summary

• Provides registered bus transceiving functionality for data storage and transfer
• Supports interface conversion between LV TTL/TTL inputs and LV CMOS outputs
• Features three-state outputs for effective bus line management

Applications

• Mobile communication systems requiring bus isolation
• Consumer products utilizing low-voltage logic interfaces
• Portable equipment needing compact registered buffer solutions

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm the specific suffix DW corresponds to the SSOP-24 package variant. Check for RoHS compliance documentation as indicated in official specifications. Ensure handling procedures adhere to ESD protection standards for CMOS devices. Validate that the procurement source provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when designing systems requiring registered bus transceivers within the 2 V to 3.6 V operating range. It is suitable for applications demanding interface compatibility between TTL and CMOS logic families. Consider the SSOP-24 package constraints for PCB layout. Evaluate the 9.5 ns propagation delay against system timing requirements. Ensure the 24 mA drive capability meets load demands for the intended circuit design.

Part Context

This part belongs to the 74LCX series, which offers low-voltage CMOS performance with TTL-compatible inputs. The LCX family is designed for portable applications due to its wide voltage range and low power consumption. Registered bus transceivers like this model integrate latching capabilities to stabilize data during transmission across buses.

Replacement Considerations

Check for MC74LCX652DG or MC74LCX652MSAX as potential pin-compatible alternatives within the same family. Verify package differences such as SOIC versus SSOP before substitution. Confirm electrical parameter equivalence regarding voltage ranges and drive currents.
