SN74LS90DE4 Overview
It is a device supplied in the 14-SOIC (0.154, 3.90mm Width) package. 14 terminations are used for its configuration. The supply voltage of 5V enables it operate in a fully flexible way. The device contains 1terminations. There are a total of 14 pins in all components. As a result, it is packaged in the way of a Tube. In the circuit, 14pins are used to connect other components. It is mounted in the way of [0]. Initially, it appears to belong to the LS family. Having been designed as a member of the 74LSseries, it is well suited to a variety of applications. The logic type of Counter, Decade is adopted. The operating temperature should be set at 0°C~70°C. This device is mounted in a Surface Mountmanner. When the supply voltage is set to [0], it is able to operate with greater reliability. Each element in the array stores 4 bits. Based on Pbfree code, this may result in yes. Further related parts can be found under its base part number 74LS90. There is 5V voltage comes from the voltage source. For the device to operate, a voltage supply of 5.25Vis required. In this case, the frequency is 42MHz Hz.
