SN54AS645J Description

Short technical summary and product information.

The SN54AS645J is an octal bus transceiver manufactured by Texas Instruments. It features 8 bidirectional channels for data transmission between two buses. Each channel can handle up to 48 mA of output current (IOL) for driving bus lines.

 

This device is part of the 54AS logic family, designed for high-speed bus interfacing. The octal configuration allows parallel data transfer, making it suitable for CPU-to-memory or I/O data buses. Its 48 mA IOL ensures strong signal integrity on long or heavily loaded bus lines.

 

Engineers should consider this transceiver for systems requiring bidirectional data flow with robust drive capability. For detailed electrical characteristics and timing specifications, refer to the official Texas Instruments datasheet.
