SN54LS390J Product Details

SN54LS390J Overview


The device is packaged in the CDIPtype. This configuration uses 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. An interconnection of 2elements is provided by wires. All component pins are equal to 16. There is a package in the form of Rail/Tube. As part of the circuit, there are 16pins that connect other components. The Through Holeway is used to mount it. In this case, it belongs to the family of [0]. As far as the device is concerned, there are 4bits of information. In this device, the temperature grade is MILITARY. From the voltage source, there is a voltage of 5V volts. To operate, the device requires a voltage of [0]. The electrical properties of the device remain stable at a maximum temperature of [0]. Generally, it is designed to operate over a range of temperatures with a lower temperature limit at -55°C. A maximum voltage of 5.5Vcan be reached by the device. Devices are capable of operating at a minimum voltage of 4.5V.
