SN74LS290D Overview
It is a device supplied in the SOIC package. In order to configure it, it uses 14terminations. The supply voltage of 5V enables it operate in a fully flexible way. The LSfamily includes it. As far as the device is concerned, there are 3bits of information. Based on the Pbfree code, the result may be no. Among the features of this electronic device, DIVIDE BY 2 AND DIVIDE BY 5 FUNCTIONSare essential. It is manufactured in the temperature grade COMMERCIAL. In this case, there is 5V voltage coming from the voltage source. The minimum supply voltage (Vsup) is 4.75V. It is possible to provide a voltage up to 5.25V (Vsup). The electronic components is from Counters family. DECADE COUNTER indicates the type of logic IC it uses. In general, the maximum operating temperature is set to 70°C.
