SN74LS90N Overview


This is a device supplied in the 14-DIP (0.300, 7.62mm) package. It is configured using 14terminations. With a supply voltage of 5V volts, it is possible to run it in a fully flexible manner. 1 elements are interconnected in wires. All component pins are equal to 14. There is a package in the form of Tube. Circuit components are connected with 14pins. It is mounted in the manner of [0]. In this case, it appears as a member of the LS family. Due to its membership in the 74LSseries, it is suitable for a variety of applications. It is decided to use the logic type [0]. In this case, the operating temperature should be set to 0°C~70°C. Mounting type Through Holeis used. Providing a voltage of 4.75V~5.25Vensures higher reliability of operation. Each element in the array stores 4 bits. Further related parts may be found under the base part number 74LS90. The voltage source generates 5Vvoltage. The device operates on a supply voltage of [0]. The frequency of the device is 42MHz.
