LM239A - Electrical characteristics

Other Parts Discussed in Thread: LM239A

Hi all,

Would you mind if we ask LM239A?

<Question1>
The data sheet shows that differential voltages are at IN+ with respect to IN-.
Just in case, both IN+ and IN- should be in the range of input common mode voltages, or not?
(Wiht only one input(+ or -) in the range, does the electircal characteristic fulfill?)

<Question2>
2-1. Out pin is open collector, right?
2-2. Regardless of the suply voltage VCC, is it OK to use another voltage for outpin?
       However, we guess the grund level  should be the same with the suply voltage VCC.
2-3. When the Out pin is applied with other voltage, how much value of volatage can it allow? 36V?

<Question3>
3-1. Regardless of the suply voltage VCC, is it OK to use another voltage for input common mode voltages?
       However, we guess that the grund level of input voltage should be the same as 2-2.
3-2. How much value of volatage can it allow for input pin? The data sheet says 30V, is it correct or not?

Kind reagrds,

Hirotaka Matsumoto
