MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 2 current is measured with no input signal and the Standby Pin (Pin 5) open.
2. Standby Supply Current (I )
STBY
The Pin 2 current is measured when the Standby Pin (Pin 5) is connected to ground.
3. Standby Terminal Current (IOS)
The Pin 5 current is measured when the Standby Pin (Pin 5) is connected to ground.
4. Threshold Voltage (High to Low) (V
)
THL(STBY)
The Pin 5 voltage is measured at the point which changes the device from operating mode into standby mode.
