74LCX652MSA

Overview

The onsemi 74LCX652MSA is an 8-bit registered bus transceiver designed for low-voltage applications. It operates within a supply voltage range of 2V to 3.6V and features 3-state outputs. The device supports LVTTL and TTL input levels while providing LVCMOS output levels, enabling effective interfacing with 5V signal environments. It incorporates D-type flip-flops for data storage and multiplexed transmission control. Key electrical parameters include a propagation delay of 9.5 ns, with high and low-level output currents rated at -24 mA and 24 mA respectively. The component is housed in an SSOP-24 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates D-type flip-flops to allow multiplexed transmission of data directly from the input bus or internal registers.
• Provides independent Output Enable pins (OEAB, OEBA) to control the direction of the transceiver function.
• Designed for low-voltage operation with capability to interface directly to 5V signal environments.

Applications

• Low-voltage memory buffer systems
• Clock distribution circuits
• Bus-oriented architectures requiring registered data transfer

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or testing standards. Confirm current availability status through authorized channels, as lifecycle changes can affect procurement options. Ensure compatibility with existing system voltage requirements before integration.

Selection Notes

Select this component when designing systems that require bidirectional data flow between buses with registered storage capabilities. It is suitable for applications needing robust interfacing between 2.5V/3.3V logic domains and 5V tolerant peripherals. Consider the SSOP-24 package constraints for PCB layout and thermal management during selection.

Part Context

This part belongs to the 74LCX series, which represents low-voltage CMOS technology optimized for high-speed performance. The LCX652 variant specifically adds registration functionality compared to non-registered counterparts like the LCX245. It serves as a critical interface element in digital systems requiring controlled data latching and bus isolation.
