Example of Application Circuit
Note 1: Connect to ground as necessary to prevent IC malfunction due to noise.
Note 2: Connect GND to signal ground on the application circuit.
Note 3:
Utmost care is necessary in the design of the output, VCC, and GND lines since the IC may be destroyed by short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by
short-circuiting between contiguous pins.
