  • LM139A: Valid spice simulation results with VCC & GND pins to tied same voltage (0V)?

    TI Thinks Resolved
    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…

  • RE: LM339: What does absolute maximum case temperature mean inside the device?

    Resolved
    This specification applies only to the FK package, i.e., to the LM139A-MIL. 60 s at 260 °C refers to the soldering process. It is specified for the case because the FK package does not have leads.

    Resolved
    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…
