CD4021BM Product Details

CD4021BM Overview


16-SOIC (0.154, 3.90mm Width) is a package containing the embedded device. Taking the total number of terminations on the chip and adding them up, we get 16. A Tube case is used to pack it. The part operates at 5V voltage. A total of 1 elements can be found on this part. It is equipped with a pin count of 16. It is recommended that the mount should be done by Surface Mount. Its mounting method is Surface Mount. -55°C~125°C is the range of operating temperatures for the device. During operation, the voltage is within the range of 3V~18V. 4000B is the series number of this electrical component. A CD4021 family can be used to search for similar parts. It is noted that this chip uses an operating supply voltage of 15V. For this part, the minimum supply voltage (Vsup) should not be less than 3V. In the device, there are 9 input lines that are available for use. A total of 8 bits are present on the IC chip. A total of 3 output lines are available for operation. It runs on a quiescent current of 100μA. It runs at 17MHz.
