MEASUREMENT METHOD

1. Supply Current (I

The Pin 2 current is measured with no input signal and the Standby Pin (Pin 5) open.

2. Standby Supply Current (I

The Pin 2 current is measured when the Standby Pin (Pin 5) is connected to ground.

3. Standby Terminal Current (I

The Pin 5 current is measured when the Standby Pin (Pin 5) is connected to ground.

4. Standby Threshold Voltage (High to Low) (V

The Pin 5 voltage is measured at the point which changes the device from operating mode into standby mode.

5. Standby Threshold Voltage (Low to High) (V

The Pin 5 voltage is measured at the point which changes the device from standby mode into operating mode.
