SN74LS290N Product Details

SN74LS290N Overview


The device is packaged in the PDIPtype. This configuration uses 14terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. In this case, it belongs to the family of [0]. As far as the device is concerned, there are 3bits of information. Based on the Pbfree code, the result may be no. It is important to note that DIVIDE BY 2 AND DIVIDE BY 5 FUNCTIONSare 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). A temperature of 70°Cis usually set as the maximum operating temperature.
