Application Method CLAMP PULSE INPUT Clamp pulse width is recommended above 15 KHz, 1.0 usec above 30 KHz, 0.5 usec above 64 KHz, 0.3 usec 16 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.
