SN74LS90DR Overview


In the 14-SOIC (0.154, 3.90mm Width)package, it is supplied. This configuration uses 14terminations. As a result of the supply voltage of 0, 5Vcan operate in a fully flexible manner. A wire connects the 1elements. A total of 14pins are available on all components. There is a package in the form of Tape & Reel (TR). In the circuit, there are 14pins that connect other parts. The way of Surface Mount is used to mount it. In this case, it appears as a member of the LS family. The 74LSseries is well suited to a number of uses. It is assumed that the logic type is [0]. It is recommended to set the operating temperature to 0°C~70°C. Using a Surface Mountmounting type, it is mounted. As a result, the device operates more reliably when a supply voltage of 4.75V~5.25Vis applied. The array contains elements that store 4bits each. Pbfree code may produce the result yes. More related parts are available under its base part number 74LS90. In order to pack the product, TRis employed. There is 5V voltage comes from the voltage source. The device requires a supply voltage of [0]. It operates with the frequency of 42MHz.
