thus the power dissipation, whenever the contending voltage

exceeds either supply.

Low Power Shutdown Mode

This CMOS transceiver all uses a fraction of the power

required by its bipolar counterparts, but it also includes a

to a 10nA trickle. This device enters shutdown whenever the

and DE = GND) for a period of at least 600ns. Disabling both

the driver and the receiver for less than 50ns guarantees

that the transceiver will not enter shutdown.

Note that receiver and driver enable times increase when the

transceiver enables from shutdown. Refer to Notes 5 through 9,

at the end of the “Electrical Specification table” on page 6, for

more information.
