APPLICATION NOTES
* Set a bypass capacitor with a capacity range from 0.1
μ
F to 1
μ
F between V
CC5IN
pin and GND pin, and between V
CC3IN
and
GND pin, each.
* V
CC5IN
voltage should be equal or more than V
CC3IN
.
* Same name pins should be connected one another.
* There is a parasitic diode between source and drain of the switch transistors. (Refer to the block diagram.) Therefore, even If
the switch may be disabled, in case the OUT voltage is higher than V
CC5IN
, some current flows from OUT to V
CC5IN
.
