Remote On/Off Signal Interface
(VIN=VIN, min to VIN, max ; open collector or equivalent,
Signal referenced to VIN- terminal)
Negative Logic: device code suffix “1”
Logic Low = module On, Logic High = module Off
Positive Logic: No device code suffix required
Logic Low = module Off, Logic High = module On
Logic Low - Remote On/Off Current
Logic Low - On/Off Voltage
Logic High Voltage – (Typ = Open Collector)
Logic High maximum allowable leakage current
