SN74AS652FN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS652FN is an AS Series, 8-bit registered transceiver featuring true outputs and a PQCC28 package. It supports bidirectional data transmission with independent control capabilities. The device includes a select input for multiplexed transmission of registered or real-time data. It operates within a standard voltage range typical for the AS logic family, with a maximum operating temperature of 70 °C and a load capacitance of 50 pF.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 8-bit registered bus transceiver functionality with true output polarity.
• Features independent control for bidirectional data flow between ports.
• Includes a dedicated select input to enable multiplexed transmission of registered versus real-time data.

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission systems requiring selection between registered and real-time data paths
• Bidirectional bus interfaces in high-speed digital logic circuits
• Registered data buffering applications in AS series logic environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches PQCC28 (LDCC28,.5SQ) and ensure lead finish complies with project requirements. Validate RoHS status as the specific part indicates non-compliance in some records; confirm environmental compliance needs before integration into final assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when AS series performance levels are required for 8-bit bidirectional data transfer. Ensure the design accommodates the 70 °C maximum operating temperature limit. Verify that the PQCC28 surface-mount package fits the PCB layout constraints. Consider the true output polarity requirement for downstream logic compatibility.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' AS (Advanced Schottky) logic family, known for high-speed operation compared to standard TTL. It functions as a registered transceiver, combining bus driving with data storage capabilities. The 8-bit width allows parallel data handling, while the registration feature provides timing synchronization for complex digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AS652N or SN74AS652D variants if different packaging is needed. Verify pinout compatibility before substituting with other 8-bit registered transceivers from the AS series. Ensure electrical characteristics match the original design requirements.
