    The worst-case idle current is 9 mA for the driver and 9 mA for the receiver. The typical load current for 100 Ω termination is 2× 31 mA; the maximum is somewhat higher, but not specified. The additional supply current for switching at 2 Mbps it not specified, but you can assume something less than about 2× 20 mA. If you want the circuit to be able to handle a shorted outputs without the supply dropping out, then it must be able to handle more than 2× 150 mA.
