MC14521BFG Product Details

MC14521BFG Overview


16-SOIC (0.209, 5.30mm Width)is a package in which this device is packaged. There are 16 terminations used for its configuration. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. In wires, 1elements are connected. In all, there are 16 pins on each component. As [0], it is packaged. A circuit is connected to other components by 16pins. To mount it, use the method of [0]. As a member of the 4000Bseries, it is ideal for a wide range of applications. It is adopted that the logic type is [0]. -55°C~125°Cis the recommended operating temperature. There is a mounting type of Surface Mounton this device. Providing a voltage of 3V~18Vensures higher reliability of operation. There are 24 bits stored in each element of the array. Its base part number, [0], contains more related parts. To operate, it requires a supply voltage of 18V volts. It is possible to supply the device with the minimum supply voltage (Vsup) of 3V. Data and clock inputs are configured at [0].
