8.2.1 Design Requirements

To design with these devices, use the parameters listed in Table 8-1.

8.2.2 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 8-2 and Figure 8-3

show the typical circuit hook-up for the devices.
