Parameters Min. Typ. Max. Unit
Input Voltage Range 0 -- 28 V
Input Voltage (Low Level) 0 -- 0.9 V
Input Voltage (High Level) 1.5 -- 28 V
Output Voltage Range 0 -- 28 V
Maximum Continuous Output Current
-- -- 1.4 V
Output Over Current Protection 1.9 2.8 3.8 V
In output mode the LSP3 GPIO can only sink current to ground. User needs
to provide adequate DC Limited Current Supply to Port#1 and Port#2 (Open
Drain).
See Figure 5.18 for detailed circuitry.
