MC14521BDR2 Product Details

MC14521BDR2 Overview


This is a device supplied in the 16-SOIC (0.154, 3.90mm Width) package. There are 16terminations used for configuring it. The supply voltage of 5V permits it to operate with full flexibility. There are 1 terminations on the device. There are a total of 16 pins in all components. As a result, it is packaged as Tape & Reel (TR). Having been designed as a member of the 4000Bseries, it is well suited for use in a wide range of applications. Divide-by-2is selected as the logic type. In this case, the operating temperature should be set to -55°C~125°C. Having a mounting type of [0], it is suitable for installation. By providing the supply voltage of [0], it is capable of operating more reliably. The array stores 24bits in each element. The result may be nowhen expressing the result in Pbfree code. There is 3V minimum supply voltage (Vsup) for this device. The device is configured with a clock and data input of 1.
