SN54LS90J Product Details

SN54LS90J Overview


A device of this type is supplied in a package of type [0]. For its configuration, 14terminations are used. This device is fully flexible due to the supply voltage of [0]. A wire connects the 1elements. 14is the number of pins on all components. It is packaged in a manner consistent with Rail/Tube. In the circuit, 14pins are used to connect other components. It is mounted in the way of [0]. In this case, it emerges as a member of the LS family. The device contains information consisting of 4bits. The temperature grade of this device is MILITARY. The voltage source generates 5Vvoltage. To operate, it requires a supply voltage of [0]. Electrical characteristics remain stable for extended periods of time at [0]. An operating temperature range is specified with a lower limit generally set at -55°C degrees Celsius. 5.5Vis the maximum voltage available to the device. As low as 4.5Vis the minimum voltage that can be applied to the device.
