The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM139DR, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM139DR Frequently Asked Questions (FAQ)
-
The LM139DR can operate from -40°C to 125°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance.
-
No, the LM139DR is a quad comparator, not a voltage regulator. It's designed for signal comparison and threshold detection, not for regulating voltage.
-
To minimize EMI effects, use proper PCB layout techniques, such as separating analog and digital grounds, using shielding, and keeping signal traces short and away from noise sources.
-
The maximum input voltage is ±30V, but it's recommended to keep the input voltage within the power supply voltage range (VCC - VEE) to ensure proper operation.
-
Yes, the LM139DR can be used as a zero-crossing detector by connecting the input signal to the non-inverting input and a reference voltage to the inverting input.
