Product Summary

The LTC1322CSW is a low power CMOS bidirectional transceiver, each featuring two reconfigurable interface ports. Each can be configured as two RS485 differential ports, as two single-ended ports, or as one RS485 differential port and one single-ended port. The LTC1322CSW can provide RS232 or EIA562 compatible single-ended outputs and additionally includes an output enable pin, allowing the receiver logic level outputs to be three-stated. The applications of the LTC1322CSW include Low Power RS485/RS422/EIA562/RS232 Interface, Cable Repeater, Level Translator.
