40Mbps, +3.3V, RS-485 Half-Duplex
Transceivers
Note 2: All devices are 100% production tested at T
Note 3: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
Note 4: DV
Note 5: Capacitive load includes test probe and fixture capacitance.
Note 6: The timing parameter refers to the driver or receiver enable delay when the device has exited the initial hot-swap protect
Note 7: Shutdown is enabled by driving RE high and DE low. The device is guaranteed to have entered shutdown after t
Note 8: Parameter is guaranteed by characterization and not production tested.
