1. CLoad includes probe and jig capacitance.

2. The response time is specified for a 150mV input step with 75mV overdrive.

3. Response time can refer to "characteristic Diagrams" Fig.1~3.

1. All output-voltage measurements are made with a voltmeter having an input impedance which is at

least 100kΩ.

2. Connect "capacitive load" (0.01uF) between output pin and ground. Do not apply any "resistor load" on

output pin, it will degrade IC's performance.
