CD4521BMT Product Details

CD4521BMT Overview


The device is packaged in the 16-SOIC (0.154, 3.90mm Width)type. This configuration uses 16terminations. By supplying 5Vwith a voltage of 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 Tape & Reel (TR). As part of the circuit, there are 16pins that connect other components. The Surface Mountway is used to mount it. Due to the fact that it is a member of the 4000Bseries, it has a wide range of applications. Logic type Divide-by-2 is adopted. Ideally, the operating temperature should be set to -55°C~125°C. This device is mounted in the Surface Mountposition. As long as the supply voltage is set to [0], the device can operate with a greater degree of reliability. An array consists of 24bits for each element. As far as the device is concerned, there are 7bits of information. Based on the Pbfree code, the result may be yes. Further related parts may be found under the base part number CD4521. For its packaging, TRis employed. As low as 3V Vsup is the minimum supply voltage. The frequency of the system is 2.5MHz.
