HEF4520BT Product Details

HEF4520BT Overview


The device is packaged in the SOICtype. 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. As part of the circuit, there are 16pins that connect other components. The Surface Mountway 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 GATED CLOCK; SCHMITT TRIGGER ON CLOCK INPUTare really important features of this electronic device. In this device, the temperature grade is INDUSTRIAL. 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 -40°C. The frequency of the system is 40MHz. A maximum voltage of 15.5Vcan be reached by the device. Devices are capable of operating at a minimum voltage of 4.5V.
