CD54HC191F3A Product Details

CD54HC191F3A Overview


The device is packaged in the CDIPtype. This configuration uses 16terminations. By supplying 4.5Vwith a voltage of 4.5V , the device can be operated in a completely flexible manner. An interconnection of 1elements 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. It is important to note that RCO OUTPUTare really important features of this electronic device. In this device, the temperature grade is MILITARY. 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 6Vcan be reached by the device. Devices are capable of operating at a minimum voltage of 2V.
