SN74LS390NS Product Details

SN74LS390NS Overview


The configuration of this device is based on 16terminations. With a supply voltage of 5V volts, it is possible to run it in a fully flexible manner. A total of 16pins are available on all components. In the circuit, there are 16pins that connect other parts. In this case, it appears as a member of the LS family. There are 4bits of information contained in the device. Using the Pbfree code, the result may be yes. Among the features of this electronic device, DIVIDE BY 2 AND DIVIDE BY 5 FUNCTIONSare essential. The device is manufactured at COMMERCIALdegrees Celsius. It is packed using [0]. The voltage source produces a voltage of 5V volts. Depending on the device type, the maximum supply voltage (Vsup) can be up to 5.25V volts. In this case, DECADE COUNTERrefers to the logic IC type being used. Temperatures above 70°Care considered to be the maximum operating temperature.
