Description
The UTC UT3222 can be placed in the power-down mode by setting PWRDOWN low, which draws only 1uA from the power
supply. When the device is powered down, the receivers remain active while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is disabled; V+ is
lowered to VCC and V- is raised toward GND. Receiver outputs also can be placed in the high-impedance state by setting EN high.
