APPLICATION NOTES:

1. Maximum input switching frequency not to exceed 20 Hz under normal conditions, or 1 Hz if output is shorted.

2. Input transitions should be <1 ms and duration and input source should be “bounceless contact” type.

3. Inductive loads must be diode suppressed.

4. Peak current that may flow when output is shorted.

5. Devices will not tolerate “short while on” at load voltages exceeding 28 VDC.
