Note 1. All voltages are with respect to ground.

Note 2. VIN, PDIN pins. Max is smaller value between (VDD+0.3)V and 4.0V

VOUT pin becomes Hi-Z at the PDN pin = “L”. Therefore the VOUT pin is available to signal line from another

device by Wired-OR. The input signal to the VOUT pin must not exceed this input voltage range.

Any voltage must not be applied to the CN pin.

WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.
