Part Number: LM139A Other Parts Discussed in Thread: LM139 I see that for this component the maximum continuous output current is 20 mA. In my design I have a zener diode regulating the output voltage of the device to 12V. Upon switching off, the zener…
Part Number: LM139A In the linked thread, it was discussed that the 20mA output current limit should not be exceeded. One of the replies suggested that infrequent excursions above this limit may have little impact on life of the product.
Is there a…
Part Number: LM139A Hello,
The datasheet for LM139A specifies an input offset voltage but only shows it as a positive value. Does that mean that the input offset voltage is always going to be a positive value, or can it also be a negative value (and…
Part Number: LM139A Other Parts Discussed in Thread: LM339 We currently have this comparator in one of our designs. The output is connected to a 6.8nF capacitor through 10 ohm resistor and the assumption is that, with 12V supply the output current will…
Part Number: LM139A Other Parts Discussed in Thread: STRIKE Hello,
What should one do with the inputs and output of the comparators that are not used with the LM139A? I see that some earlier versions of the datasheet recommend tying both inputs and…
Part Number: LM139A Other Parts Discussed in Thread: LM393 Team,
My customer has the following question on SLCS006T:
After a morning of confusion, we believe we have spotted a typo in the LM139A datasheet, revised June 2015. Page 10, section 8.3,…
Part Number: LM139A-MIL I need the materials and finishes ( and thicknesses if available) of the leads and package for this device. Also the non-operational storage temp range.
Hello Kirby,
thank you for your fast response.
I´m interested in the LM139AWGRLQMLV (DSCC# 5962R9673802VXA).
The datasheet ID is SLCS161 from june 2017.
Kind regards,
Thomas
Hello Carl, I do not know of any heavy ion testing on this exact version of the LM139AQML-SP (ELDRS-free) above the 40.6MeV-cm2/mg testing described in my paper. Since this is a bipolar product, SEL would be unexpected. There has been many tests done…
Part Number: LM139A Hello -- there is an LM139AD being used in a circuit design that I'm analyzing in TINA for failure modes/reliability purposes. When the device's VCC & GND pins are tied to 0V, I can still toggle the correct open-collector output conditions…
