Notes:

1. Bypassing the power supply line is

required with a 0.1

µF ceramic disc

capacitor adjacent to each optocoupler

as illustrated in Figure 19. The power

supply bus for the optocoupler(s)

should be separate from the bus for

any active loads, otherwise a larger

value of bypass capacitor (up to

0.5

µF) may be needed to suppress

regenerative feedback via the power

supply.

2. Peaking circuits may produce transient

input currents up to 100 mA, 500 ns

maximum pulse width, provided

average current does not exceed 5 mA.
