Notes to the characteristics
1.
This current is the maximum allowed into the inputs when line and field flyback signals are connected to these inputs.
Series current limiting resistors must be used to limit the input currents to
±
1 mA.
2.
Can be pulled higher by external pull-up resistor, (maximum leakage current
≈
200
μ
A).
