Alternate Parts for LM139N
This table gives cross-reference parts and alternative options found for LM139N. 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 LM139N, 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.
LM139N Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is the supply voltage (VCC) + 0.3V. Exceeding this voltage can cause damage to the device.
-
To prevent oscillation, add a small hysteresis (typically 1-10mV) to the input signal or use a Schmitt trigger configuration. This helps to ensure a clean transition between the high and low output states.
-
The minimum input impedance required is typically around 10kΩ. If the input impedance is too low, it may affect the comparator's accuracy and stability.
-
No, the LM139N is a comparator, not an amplifier or op-amp. It is designed to provide a digital output based on the comparison of two input voltages, not to amplify signals.
-
The pull-up resistor value depends on the load current and the desired output voltage. A general rule of thumb is to choose a value between 1kΩ and 10kΩ. A higher value reduces power consumption but increases the output rise time.
