<Notes of input signals>

The longer rising and falling slew rate of input signals in hybrid IC, the more ringing signals on input signals increase,

because input signals get ringing voltage VIG of GND wiring. Especially, when capacitances are connected output

pins 2, 3, 4, 5 for preventing radiation noise, ringing signals increase by discharge and charge current in these.

These ringing signals amplitude are input hysteresis voltage 0.6V over. Therefore, the driver actions in error, and it is

destroyed by over current. So apply input signal slew rate as short as possible. We recommend using direct input to

the driver by CMOS IC of HC model.
