... Driver The driver provides full RS485/RS422 compatibility. When enabled high, Y-Z is positive for the full-duplex devices (LTC2851, LTC2852) and A-B is positive for the half-duplex device (LTC2850). When the driver is disabled, both outputs are high-im- pedance. For the full-duplex devices, the leakage on the driver output pins is guaranteed to be less than 10μ ...
