Frequently Asked Questions
What is the input bias current of the LM139DR?
The LM139DR has a typical input bias current (IIB) of 0.025µA at 25°C, with a maximum of 0.3µA. This ultra-low bias current minimizes loading on the input signal source, making it suitable for high-impedance sensor interfaces and precision threshold detection circuits.
What are the typical applications of the LM139DR?
The LM139DR is commonly used in voltage level detection, window comparators, logic signal interfacing, wired-OR bus configurations, LED or relay driving, battery voltage monitoring, power supply supervisory circuits, and analog-to-digital conversion front ends in industrial and consumer electronics.
What package does the LM139DR come in and what are its output characteristics?
The LM139DR is housed in a 14-pin Small Outline IC (SOIC) package (JESD-30 code R-PDSO-G14). It features open-collector and open-drain outputs, which allow multiple comparators to share a common bus line (wired-OR) and interface directly with various logic families by connecting an external pull-up resistor.
Is the LM139DR RoHS compliant and what is its longevity rating?
Yes, the LM139DR is Pb-free and RoHS compliant (JESD-609 code e4). Texas Instruments has assigned it a YTEOL (Years To End Of Life) rating of 15 years, indicating long-term production commitment and making it a reliable choice for designs requiring extended product availability.
