Low Power Shutdown Mode

This BiCMOS transceiver uses a fraction of the power

required by their bipolar counterparts, but it also includes a

to a 50nA trickle. It enters shutdown whenever the receiver

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

driver and the receiver for less than 60ns 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 8, 9,

10, 11 and 12, at the end of the “Electrical Specifications”

table on page 6, for more information.
