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