SNJ54LS197FK Overview


In order to configure it, it uses 20terminations. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. There are 20pins on all components. In this case, it appears as a member of the LS family. In the device, the information consists of 4 bits. Pbfree code may result in no. These electronic devices have many important features, and DIVIDE BY 2 AND DIVIDE BY 8 FUNCTIONSis one of them. 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. Depending on the device type, the maximum supply voltage (Vsup) can be up to 5.5V volts. This part is from the family [0]. This logic IC is of type [0]. Temperatures above 125°Care usually the maximum operating temperatures. In general, -55°Cis considered to be the minimum operating temperature.
