The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state. 6. The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger signals, 300 ns is typical. ] 2 MOTOROLA ANALOG IC DEVICE DATA LM339, LM339A, LM239, LM239A, LM2901, M2901V, MC3302 Figure 2.

This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (VOL to VOH). To alleviate this situation input resistors < 10 kΩ should be used. The addition of positive feedback (< 10 mV) is also recommended. It is good design practice to ground all unused input pins. Differential input voltages may be larger than supply voltages without damaging the comparator’s inputs. Voltages more negative than –300 mV should not be used. Figure 9.
