Frequently Asked Questions
What supply voltage range does the LM239NE4 support?
The LM239NE4 operates from a single supply voltage ranging from 2V to 36V, or dual supplies up to ±18V. This wide supply range makes it suitable for a broad variety of analog and mixed-signal applications.
What type of output does the LM239NE4 have and how can it be used?
The LM239NE4 features open-collector (open-drain) outputs on each of its four independent comparator channels. These outputs allow wired-OR configurations, direct interfacing with different logic families (TTL, CMOS), and pull-up to voltages independent of the supply rail, providing flexible system integration.
What are typical applications for the LM239NE4?
The LM239NE4 is commonly used in threshold detection circuits, window comparator designs, voltage level shifting, zero-crossing detection, and relay driver applications. Its quad comparator configuration allows multiple sensing functions to be implemented in a single 14-pin DIP package.
What is the input offset voltage specification for the LM239NE4?
The LM239NE4 specifies a maximum input offset voltage of 5mV (5000µV) at room temperature. This parameter is important when precise voltage comparison thresholds are required, as offset voltage directly affects the accuracy of the switching point.
What temperature range and package does the LM239NE4 support?
The LM239NE4 is housed in a 14-pin plastic DIP (PDIP) package with the 'E4' JEDEC moisture sensitivity designation, indicating it is lead-free and RoHS-compliant. It is rated for operation across industrial temperature ranges, making it suitable for both commercial and industrial environments.
