Note 1. All voltages 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 PDN pin = “L”. Therefore VOUT pin is available to signal line from another device
by Wired-OR. Then the input signal to VOUT pin mustn’t exceeds this input voltage range.
The 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.
