LM239DR2 Product Details

LM239DR2 Overview


The product is packaged in SOIC in order to facilitate transportation.Output type of this comparator is TTL .The part is shipped by Cut Tape (CT) .The comparator has 14 terminals.The electrical component in this case belongs to the Comparator family.This comparator is capable of handling a wide range of tasks if it is supplied with a voltage of 5V .This is a typical comparator of type General Purpose .The device includes 14 pins.14 pins are available on the comparator.In order to find a solution that meets your specific needs, search LM239 for more pin-to-pin solutions.A quiescent current of 2.5mA is observed in this comparator.A Surface Mount is provided for mounting it onto a PCB or another board.Normal use of the device should require a nominal supply current of 2mA .An excess of current supply over 2mA could result in malfunction of the comparator.A power supply of 5V is sufficient for the operation of the device.The voltage gain of the part is indicated by 106.02dB in the voltage formula.There is no recommendation for temperatures higher than 85°C .Temperatures below -25°C are not suitable for the device.Compatibility is defined as 36V when the comparator is operating at its maximum supply voltage.A minimum supply voltage of 3V is allowed for this comparator.The output quality of 4 channels is maintained by cooperating with each other.
