M61303FP
Application Method
Clamp Pulse Input
Clamp pulse width is recommended
above 15 kHz, 1.0 μs
above 30 kHz, 0.5 μs
above 64 kHz, 0.3 μs.
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 figure shown right is recommended.

Notice of Application
1. Recommended pedestal voltage of IC output signal is l V.
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 coupling cap (0.01 μ) as nearer as can to VCC pin. If not response of waveform is getting wrong.
