Notes:

1. For proper operation, a 10nF bypass capacitor should be

For complete emissions protection a C1 = 68nF is

recommended.

Notes:

1. For proper operation, a 10nF to 100nF bypass capacitor should be placed as close

2. The device could tolerate negative voltage down to -24V, so if negative transients

- the resistor has to withstand the power dissipated in both over voltage

3. The device could tolerate positive supply voltage up to +27V (until the maximum

power dissipation is not exceeded), so if positive transients over supply line with

network should be sized to limit the voltage over the device below the maximum

allowed.
