Recommended Application Circuit
The values for the devices are all recommended values. For values under each input condition, see the
above-mentioned recommended operating conditions.
(Example : f
For the data to be input, see the section on the recommended input data.
Because there may be shorts between outputs, shorts to supply, or shorts to ground, be careful when designing
output lines, V
SGND
Note: We recommend the user add bypass capacitors as required.
5 V
Make sure as much as possible that GND wiring has only one contact point.
Also, make sure that the VM pins are connected.
