Overview of LM139J/PB by Texas Instruments
The LM139J/PB is a low power, low offset voltage quad comparator, designed in a 14-CDIP package. It operates within a temperature range of -55 to 125 degrees Celsius and is encapsulated in a ceramic, glass-sealed package. This component features open-collector and open-drain outputs, with a maximum supply voltage limit of 36 volts, and a typical supply voltage of 5 volts. The device has four comparator functions, each with a maximum input offset voltage of 5000 µV and a nominal response time of 1300 ns. The LM139J/PB does not comply with the RoHS code.
Significantly, the package is a dual in-line package (DIP), and it’s notable for its lead-through-hole terminal configuration, emphasizing its traditional mounting style. With a maximum bias current of only 0.3 µA and a maximum supply current of 2 mA, the LM139J/PB is a model of efficiency for applications requiring precise voltage comparisons with minimal power outlay. Given its robust operational temperature range and specific packaging qualities, this product underscores its suitability for harsh environments and rigorous operational conditions typical of military-grade components, despite not being qualified explicitly for defense standards.
