74LCX652MSAX

Overview

The onsemi 74LCX652MSAX is an octal bus transceiver with registered outputs, designed for low-voltage applications. It operates within a supply voltage range of 2 V to 3.6 V and features 5V tolerant inputs and outputs. The device provides eight channels in a 24-pin SSOP package. Key electrical parameters include a propagation delay of 9.5 ns, output currents of ±24 mA, and a maximum operating temperature of +85 °C. It supports LVTTL and TTL input levels while delivering LVCMOS output levels.

Feature Summary

• Integrated D-type flip-flops allow data to be clocked into internal registers from the input bus or transmitted directly.
• Provides independent control over data transmission direction via dedicated Output Enable pins (OEAB, OEBA).
• Features 5V tolerant I/O capabilities, enabling safe interfacing between low-voltage logic and 5V signal environments.

Applications

• Low-voltage memory buffer applications
• Clock driver circuits
• Bus-oriented communications systems

Procurement Notes

Verify component authenticity through authorized distributors as this part number may have limited availability. Confirm that the specific suffix matches the required package type and tape-and-reel specifications. Check for RoHS compliance documentation to ensure adherence to current environmental regulations. Validate lead times due to potential discontinuation status associated with older LCX series components.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer with latching capability at low voltages. Ensure the design accommodates the 2 V to 3.6 V supply range and utilizes the 24-lead SSOP footprint. Consider the 9.5 ns propagation delay for timing constraints. Verify that input drivers support LVTTL or TTL logic levels to guarantee proper signal recognition across the operating temperature range.

Part Context

This device belongs to the 74LCX family of CMOS logic integrated circuits manufactured by onsemi. The LCX series is characterized by its compatibility with both 3.3 V and 2.5 V power supplies while maintaining performance suitable for high-speed digital applications. The 652 variant specifically combines transceiver functionality with register storage, distinguishing it from standard unregistered bus drivers.

Replacement Considerations
