Product Summary

The LTC1323CSW#TR is a multi-protocol line transceiver designed to operate on AppleTalk or EIA562-compatible single ended networks while operating from a single 5V supply. There are two versions of the LTC1323CSW#TR available: a 16-pin version designed to connect to an AppleTalk network, and a 24-pin version which also includes the additional single-ended drivers and receivers necessary to create an Apple-compatible serial port. An on-board charge pump generates a -5V supply which can be used to power external devices. Additionally, the 24-pin LTC1323CSW#TR features a micropower keep-alive mode during which one of the single-ended receivers is kept active to monitor external wake-up signals. The LTC1323CSW#TR draws only 2.4mA quiescent current when active, 65mA in receiver keep alive mode, and 0.5mA in shutdown, making it ideal for use in battery-powered systems. The applications of the LTC1323CSW#TR include LocalTalk Peripherals, Notebook/Palmtop Computers, and Battery-Powered Systems.
