LINEAR LTC1345 Data Sheet
Summary
The LTC1345 is a robust single-chip V.35 transceiver delivering both clock and data signals for reliable communication interfaces. Designed to operate entirely from a single 5V supply, it features three independent transmitters and receivers with built-in ESD and short-circuit protection. This manual provides comprehensive technical specifications, electrical characteristics, operating ranges, and application details necessary for integrating the component into complex electronic systems. It is essential documentation for hardware engineers and industrial designers building equipment that requires standardized V.35 connectivity ports (DTE or DCE).
