These comparators are designed for use in level detection, low–level
sensing and memory applications in consumer automotive and industrial
electronic applications.
• Single or Split Supply Operation
• Low Input Bias Current: 25 nA (Typ)
• Low Input Offset Current: ±5.0 nA (T yp)
• Low Input Offset V oltage: ±1.0 mV (Typ) LM139A Series
4.At the output switch point, VO ] 1.4 Vdc, RS ≤ 100 Ω 5.0 Vdc ≤ VCC ≤ 30 Vdc, with the inputs over the full common mode range
(0 Vdc to VCC –1.5 Vdc).
5.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.
These quad comparators feature high gain, wide
bandwidth characteristics. 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.
