1) Measuring conditions are as listed in supplementary Table. Measured with a current meter at test point IA. 2) Decrease Main Bat or Sub Bat gradually, and measure the voltage when the bottom of waveform output is distorted. The voltage is called VOL. Next, increase V30 gradually, and measure the voltage when the top of waveform output is distorted. The voltage is called VOH.Voltage Vomax is calculated by the equation below: Vomax =VOH-VOL

Application Method

The clamp pulse circuit in ordinary set is a long round about way, and beside high voltage, sometimes connected to external terminal, it is very easy affected by large surge. Therefore, the Fig. shown right is recommended.
Notice of application
1.Recommended pedestal voltage of IC output signal is 1V. 2.This IC has 2 Input routes. When the 2 Input signal input at different timing,clamp pulses which synchronize with selected signals is needed. In this case,it is necessary to change clamp pulses by the outside circuit. 3.Connect cuppling Cap(0.01u) as nearer as can to Vcc Pin. If not response of waveform is getting wrong.
