SNJ54LS197W Product Details

SNJ54LS197W Overview


It is configured using 14terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. In total, there are 14pins on the component. Initially, it appears to belong to the LS family. There is information in the device in the form of 4bits. As far as Pbfree code is concerned, the result may be no. An important feature of this electronic device is [0]. Temperature grade MILITARYhas been selected for this device. As a result of the voltage source, there is 5V voltage. The minimum supply voltage (Vsup) is 4.5V. Up to a maximum voltage of 5.5Vcan be supplied (Vsup). It is part of the Countersfamily of electronic components. It uses the logic IC type [0]. Temperatures above 125°Care usually the maximum operating temperatures. In most cases, a minimum operating temperature of -55°Cis set.
