... MC1489, A APPLICATIONS INFORMATION turn–on voltage of 1.25 V and turn–off of 1.0 V for a typical hysteresis of 250 mV. The MC1489A has typical turn–on of 1.95 V and turn–off of 0.8 V for typically 1. hysteresis. Each receiver section has an external response control node in addition to the input and output pins, thereby allowing the designer to vary the input threshold voltage levels ...
