7.4 Device Functional Modes
7.4.1 Power Down Mode
The DS90CR286A and DS90CR216A may be placed into a power down mode at any time by asserting the PWR
DWN pin (active low). The DS90CR286A and DS90CR216A are also designed to protect themselves from
accidental loss of power to either the transmitter or receiver. If power to the transmit board is lost, the receiver
clocks (input and output) stop. The data outputs (RxOUT) retain the states they were in when the clocks stopped.
When the receiver board loses power, the receiver inputs are shorted to V_CC through an internal diode. Current is
limited to 5 mA per input, thus avoiding the potential for latch-up when powering the device.
