LM139D Overview

Electronic comparator is packaged in 14-SOIC (0.154, 3.90mm Width) for convenient transportation.This comparator is of the CMOS, MOS, Open-Collector, TTL output type.Ready for shipping in Tube package.You can find 14 terminals of the comparator.Other Comparator like the device play a important role in the industry.Supplied by 5V voltage, the comparator can accomplish the many demanding tasks.Speaking of types, this is a typical Differential comparator.This is a 4 element comparator.The pinout of the component starts from 14 pins it has.Surface Mount universial mout for easy adapting.The operating temperature should be set to -55°C~125°C to avoid mal-function.The comparator has 14 pins.Try search LM139 to get more pin-to-pin solutions for your special needs.This comparator presents a quiescent current of 2mA .Electronic comparator has a Surface Mount for mounting on PCB or other boards.For normal use of the device, the nominal supply current should be 2mA .Current supply exceeding 500μA could cause disfunction of the compartator.5V power supplies are enough to run the device.The maximal current your can input into the device is 100nA .From the voltage formula, the voltage gain of the part is 106.02dB .Normal operation requires 3V operating supply voltage.Packed in TR , this device is for general uses (often in ADC circuits).
