SN74LS90DRE4 Product Details

SN74LS90DRE4 Overview


In the SOICpackage, it is supplied. In order to configure it, it uses 14terminations. As a result of the supply voltage of 0, 5Vcan operate in a fully flexible manner. There are wires connecting 1elements. The total number of component pins is 14. Packaging is based on Tape & Reel (TR). To connect the circuit's other components, there are 14pins. Using [0], it can be mounted. In this case, it appears as a member of the family [0]. In this device, there is information of 4bits. It is possible for the result to be yesin Pbfree code. The device is manufactured at a temperature grade of COMMERCIAL. In order to pack the product, TAPE AND REELis employed. From the voltage source, there is 5Vvoltage. The device requires a supply voltage of [0]. Electrical characteristics are stable at temperature 70°Cfor extended periods of time. It operates within a specified temperature range, with the lower limit typically set at 0°C degrees Celsius. 42MHzis the frequency of operation. In this case, the maximum voltage available to the device is 5.25V. A minimum voltage of 4.75Vis available for the device.
