(2) Power Down sequence
Capacitors for Power supply and pin arrangement
1. Capacitors for power supply
2. Pin arrangement of the test pins (pins 15 and 16)
The capacitors C2 and C3 for power supply connected between IC pins must be inserted using the shortest lines
possible.
The test pins (pins 15 and 16) are used as pins for testing before shipment. These pins are not used normally. Therefore,
these pins must be left open if the pin arrangement is not performed. Please make sure to connect these pins to GNDs if
the pin arrangement is performed.
The OFF Time should secure more than 100msec for reduction of the popping noise.
