SN54LS90J Overview


This device is supplied in the CDIP package. The configuration of this device is based on 14terminations. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. An interconnection of 1elements is provided by wires. The number of all component pins is 14. Rail/Tubeis the packaging method used for this package. In the circuit, there are 14pins that connect other parts. The way of Through Hole is used to mount it. Initially, it appears to belong to the LS family. As far as the device is concerned, there are 4bits of information. A temperature grade of MILITARYis specified for this device. In this case, 5Vvoltage is generated by the voltage source. The device operates on voltage [0]. Long-term operation at 125°Cwith acceptable electrical stability is possible. Generally, the temperature limit is set at -55°Cso it will operate over a specified range. In this case, the maximum voltage available to the device is 5.5V. There is a minimum voltage available for the device of 4.5V.
