CD74HC190NS Overview


For its configuration, 16terminations are used. Having a voltage supply of 4.5Vallows it to operate in a highly flexible manner. 16is the number of pins on all components. In the circuit, 16pins are used to connect other components. The HC/UHfamily is derived from it. There is information in the device in the form of 4bits. The result may be yesin terms of Pbfree code. Among the features of this electronic device, RCO OUTPUTare essential. The device is manufactured at a temperature grade of MILITARY. TR is employed for its packing. The voltage source generates 2/6Vvoltage. It is possible to supply the device with the minimum supply voltage (Vsup) of 2V. Up to 6Vis the maximum supply voltage (Vsup). The electronic part belongs to the Counters family. A logic IC with the type DECADE COUNTERis used. A temperature of 125°Cis usually set as the maximum operating temperature. A common practice is to set the minimum operating temperature to -55°C.
