11. Technical Reference
Inputs have:
Hysteresis (generally of about 0.5 V).
l
A threshold level of about +1.5 V.
l
An input impedance of about 5000 ohms connected to GND (defaults to a -ve voltage state with nothing attached).
l
An acceptable input range of +/-15 V.
l
Outputs have:
A voltage swing ranging from +/-5 V to +/-12 V (depends on hardware).
l
A source current drive capability of about 15 mA (with output current limiting). This can drive LEDs or provide a voltage for
l
contact closure applications.
