LM139J Overview

A convenient transport package is provided in CDIP .The comparator has a OPEN-COLLECTOR output.There are 14 terminals on the comparator.The electrical component in this case belongs to the Comparator families.A comparator is capable of completing a variety of demanding tasks when supplied with 5V voltage.As a result, it contains 14 pins.The comparator is equipped with 14 pins.The PCB or other board has a Through Hole for mounting.Electronic comparator is possible for the comparator to malfunction when the current supply exceeds 2mA .Comparator electronics is apparent from the voltage formula that the voltage gain for the part is 106.02dB .An increase in temperature over 125°C is not recommended.Comparator electronics cannot be operated at a temperature lower than -55°C .In the comparator, the maximum supply voltage is 30V .Comparator electronics is possible to operate this comparator wComparator electronicsh a minimum supply voltage of 2V .As a result, 4 channels work together to maintain the quality of the output.A comparator consists of a high-gain COMPARATOR amplifier.The normal operation of the system requires 3V operating voltage.
