DISCRETE IN* pins:
INACTIVE: 10 ≤ Vin ≤ 33VDC or Rin ≥ 100kΩ
ACTIVE: Vin ≤ 1.9VDC with ≥ 75 uA sink current, or Rin ≤ 375Ω
Sink current is internally limited to 200 uA max for a grounded input
DISCRETE IN pins:
INACTIVE: Vin ≤ 3.5VDC or open
ACTIVE: 6.5 ≤ Vin ≤ 33VDC with ≥ 75 uA source current
Source current is internally limited to 1.5 mA max for a 10-33VDC input
DISCRETE OUT* pins:
INACTIVE: Floating (can be pulled up to externally sourced Vout in the range 0 ≤ Vout ≤ 33VDC)
Leakage current in the INACTIVE state is typically ≤ 10 uA to ground
ACTIVE: Vout ≤ 0.5VDC with ≤ 20 mA sink current
Sink current must be externally limited to 20 mA max
ANNUNCIATE* pins:
INACTIVE: Floating (can be pulled up to externally sourced Vout in the range 0 ≤ Vout ≤ 33VDC)
Leakage current in the INACTIVE state is typically ≤ 250 uA to ground
ACTIVE: Vout ≤ 0.5VDC with ≤ 500 mA sink current
Sink current must be externally limited to 500 mA max
