74ABT16646CSSC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT16646CSSC is a registered bus transceiver belonging to the ABT series. It features two functional units, each handling eight bits of data, resulting in a total 16-bit configuration with true outputs. The device utilizes BiCMOS technology and is housed in a 56-pin SSOP package (PDSO56) with dimensions of 0.300 inches. It operates within a maximum temperature range of 85 °C and includes direction control capabilities.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Registered bus transceiver architecture supporting bidirectional data flow
• Dual independent 8-bit functional blocks for parallel processing
• Direction control functionality for managing transmission paths

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus interfaces requiring registered buffering
• System memory mapping and address bus management
• Parallel communication links between microprocessors and peripherals

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity as Rochester Electronics sources these parts from original manufacturers or surplus channels. Confirm that the specific marking matches the original factory specifications. Check for lead-free compliance and RoHS status if required by your assembly process. Ensure the SSOP-56 package condition meets your quality standards before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a registered 16-bit bus interface is needed with ABT speed characteristics. It is suitable for designs requiring true outputs and independent direction control for two separate 8-bit buses. Consider the 56-pin SSOP package constraints for PCB layout. Verify voltage levels match your system requirements against standard ABT specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the broader 74ABT16646 family, which includes variants like the SN74ABT16646DLR from Texas Instruments. While the core logic function remains consistent across manufacturers, packaging and specific electrical parameters may vary. The CSSC suffix typically denotes a specific package and temperature grade combination offered by Fairchild or its successors.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ABT16646DLR from Texas Instruments serves as a direct functional equivalent. Both are 16-bit registered bus transceivers with similar pinouts and logical operations. Verify package compatibility and ensure electrical characteristics align with your design margins before substitution.
