CD4521BMT Overview


A device of this type is supplied in a package of type [0]. It is configured with 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. The device contains 1terminations. All component pins are equal to 16. It is packaged in the way of Tape & Reel (TR). In the circuit, there are 16pins that connect other parts. It is mounted in the way of [0]. Having been designed as a member of the 4000Bseries, it is well suited for use in a wide range of applications. Divide-by-2is used as the logic type. -55°C~125°Cshould be set as the operating temperature. This device is mounted in a Surface Mountmanner. It is able to operate with higher reliability when the supply voltage of 3V~18V is provided. The array stores 24bits in each element. There is information in the device in the form of 7bits. Based on Pbfree code, this may result in yes. Further related parts may be found under the base part number CD4521. TR is employed for its packing. There is 3V minimum supply voltage (Vsup) for this device. Frequency 2.5MHzdetermines its operation. The electronic components is from Counters family.
