LM139JB Information

General Description

LM139JB is a General Purpose Comparator from Texas Instruments, providing high-quality and reliable performance in various applications. This open-collector, open-drain, rail-to-rail comparator has a wide operating range of -55°C to 125°C, making it suitable for use in a broad spectrum of devices. The LM139JB's input offset voltage is as low as 5mV at 5V supply, ensuring precise comparisons and reducing errors. Its high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) enable the device to operate effectively even in the presence of noise or interference. The comparator has a typical propagation delay of 300ns, making it suitable for applications requiring fast response times. The LM139JB also features a hysteresis-free design, allowing for smooth transitions between logic levels. Its compact 14-CDIP package and through-hole mounting type make it easy to integrate into existing designs.
