LT1785IS8-PBF Product Details
The LT®1785/LT1791 are half-duplex and full-duplex differ ential 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 out putscontrol EMI emissions and improve data transmis sion integrity on improperly terminated lines. Drivers are specifi ed to operate with inexpensive cables as low as 72Ω characteristic impedance.
The LT1785A/LT1791A devices have “fail-safe” receiver inputs to guarantee a receiver output high for shorted, open or inactive data lines. On-chip ESD protection eliminates need for external protection devices.
