11 / 16 page 11 FN6587.1 February 18, 2008 Low Power Shutdown Mode This BiCMOS transceiver uses a fraction of the power required by their bipolar counterparts, but it also includes a shutdown feature that reduces the already low quiescent ICC to a 50nA trickle. It enters shutdown whenever the receiver and driver are simultaneously disabled (RE =VCC and 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.
