SN74LS190N Product Details

SN74LS190N Overview


The device is packaged in the PDIPtype. This configuration uses 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. All component pins are equal to 16. In this case, it belongs to the family of [0]. As far as the device is concerned, there are 4bits of information. Based on the Pbfree code, the result may be no. It is important to note that TCO OUTPUTare really important features of this electronic device. In this device, the temperature grade is COMMERCIAL. From the voltage source, there is a voltage of 5V volts. As low as 4.75V Vsup is the minimum supply voltage. It is possible to provide a voltage up to 5.25V (Vsup). Countersis the family name of the electronic part. DECADE COUNTER indicates the type of logic IC it uses. A temperature of 70°Cis usually set as the maximum operating temperature.
