Product Summary

The LT1785CS8#PBF is a RS485/RS422 Transceiver. The LT1785CS8#PBF is half-duplex and full-duplex differential bus transceivers for RS485 and RS422 applications which feature on-chip protection from overvoltage faults on the data transmission lines. Receiver input and driver output pins can withstand voltage faults up to ±60V with respect to ground with no damage to the device. Faults may occur while the transceiver is active, shut down or powered off. Data rates to 250kbaud on networks of up to 128 nodes are supported. Controlled slew rates on the driver outputs control EMI emissions and improve data transmission integrity on improperly terminated lines. Drivers are specified to operate with inexpensive cables as low as 72Ωcharacteristic impedance. The applications of the LT1785CS8#PBF include Industrial Control Data Networks, CAN Bus Applications and HVAC Controls.
