MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 1 current is measured with no input signal and the Standby Pin (Pin 5) open.
2. Standby Supply Current (ISTBY)
The Pin 1 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 Pin 5 is connected to ground.
4. Threshold Voltage (High to Low) (VTHL)
The Pin 5 voltage is measured at the point which changes the device from operating mode into standby mode.
5. Threshold Voltage (Low to High) (VTLH)
The Pin 5 voltage is measured at the point which changes the device from standby mode into operating mode.
6. Clamp Voltage (VCMP)
The DC voltage at Pin 2 is measured with no input signal.
