Multipoint Differential Communication
The LTC491 combines a differential transmitter and receiver for robust communication over balanced twisted-pair wiring. Three-state controls allow the driver and receiver to be enabled independently on shared buses.
Low-Power CMOS Interface
CMOS construction reduces supply current while maintaining the common-mode tolerance required for industrial RS-485 links. The CS suffix identifies the surface-mount SOIC version.
