CD4521BPWRG4 is a popular piece of integrated circuit (IC) form Texas Instruments. Also known as a CMOS counter/divider circuit, it is used in many applications to detect and adjust the functioning of devices.

CD4521BPWRG4 is classified as a logic - counter, divider type of IC. It is available in 14-pin dual in line (DIP) package, which is further through-hole mounted. The pin out looks like this:

• Pin 1: Clear (CLR)
• Pin 2: Clock Enable (CPE)
• Pin 3:Data Output (Q1)
• Pin 4: Data Output (Q2)
• Pin 5: Data Output (Q3)
• Pin 6: Data Output (Q4)
• Pin 7: Data Output (Q5)
• Pin 8: Data Output (Q6)
• Pin 9: Output Enable (P)
• Pin 10: Clear (CLR)
• Pin 11: Clock Input (CP)
• Pin 12: GND
• Pin 13: VCC
• Pin 14: NC

The IC is an 8-stage binary Counter and Divide-by-N counter. It is capable of counting from 0 to 255. The IC performs three basic operations — Count up, Hold, and Reset. It has also got Power-On Reset feature, which clears the counter whenever VCC voltage is applied to the device. It is capable of operating from a voltage range of 2 V to 6 V, consuming a current of around 500 uA.

CD4521BPWRG4 is designed to count in two different modes: Synchronous and Asynchronous modes. In synchronous mode, the counting is done by using the clock input (CP pin). When the clock edges arrive consecutively at the clock input, the counter is incremented by one. In the asynchronous mode, the CLK pin is connected to the Ground and the counter is incremented or cleared by the asynchronous inputs CLR and CLK.

The CD4521BPWRG4 IC is used in many industrial applications. Its primary application is as a clock generator in devices such as audio systems, DC motors and computers. Its ability to count up to 255 cycles makes it a popular choice for controlling various kinds of operations in these devices. It is also used for timing and sequencing applications because of its ability to produce a pulse output. CD4521BPWRG4 IC can also be used as a divider to create a frequency that is at a specific harmonic of an incoming signal.

CD4521BPWRG4 is a versatile IC that can be used in many different applications. Its versatile nature and design make it an ideal choice as it can be used for counting, timing, sequencing, and frequency division. Furthermore, its low current requirement and wide range of operating voltages make it an attractive option for many applications.
