9.2.2 Detailed Design Procedure

Unlike optocouplers, which require external components to improve performance, provide bias, or limit current,

the ISO773x family of devices only requires two external bypass capacitors to operate. Figure 21 and Figure 22

show the typical circuit hook-up for the devices.
