PRODUCTION DATA.
If a high-level input (> 0.75 VCC) is applied to RS (pin 8), the circuit enters a low-current, listen-only standby mode during which the driver is switched off and the receiver remains active. The local controller can reverse this low-power standby mode when the rising edge of a dominant state (bus differential voltage > 900-mV typical) occurs on the bus.
