SNJ54LS191FK Product Details

SNJ54LS191FK Overview


It is configured using 20terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. In this diagram, there are 1elements that are interconnected by wires. In this case, it is packaged as Rail/Tube. Circuit components are connected by 20pins. It is mounted using the way of [0]. Initially, it appears to belong to the LS family. There is information in the device in the form of 4bits. 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. In order for it to operate, it requires a supply voltage of 5V . Long-term operation at 125°Cwith acceptable electrical stability is possible. It operates over a specified temperature range with a lower limit generally set to -55°C. The maximum voltage that can be applied to the device is 5.5V. It is possible to operate the device at as low a voltage as 4.5V.
