The CD4516BEG4 is a useful and versatile BCD (Binary Coded Decimal) down counter. As a member of CD4516 series, this IC comprises of four cascaded BCD counters and it has the capability to clock a group of up to four BCD decimal counters. It counts from 15 to 0 by utilizing a clock input. Depending on the fact whether the active low terminals present at the outputs of the IC are given a logical ‘high’ or ‘low’, one may control the operation of the counter. This IC is well suited for applications in which BCD down counting is preferred and has been used in various digital and embedded electronics designs due to its small size and increased efficiency.

The CD4516BEG4 is equipped with 15 stages that are internalized in the chip. It has active low terminal outputs which reduce the count to 0 and a clock pin, used to input signal pulses. When other pins are grounded, the counter starts functioning and counting down. It features a very high speed and has good ripple effect immunity as well.

To meet the customers’ various needs, the CD4516BEG4 is packed in a range of packages. It can be used in configurations such as 16-pin DIP, 16-pin SOIC, 20-pin TSSOP, and even in 24-pin plastic DIP for larger single- or multi-unit orders.

The CD4516BEG4 is useful for achieving simple waveform generation due to its ability to control the timing of monostable flip flops, one pulse per count and simple programmable logic arrays of all types, for instance in mixing, encrypting or decrypting data and for multiple up-/down-/bidirectional counting purposes.

The operation of CD4516BEG4 can be explained with the help of a simple circuit. The IC is connected to an external clock source and it is ready to count the number of clock pulses. The outputs of the four stages are available at outputs 0-3. Outputs 0, 1 and 2 can be used to obtain the three BCD bits, while output 3 provides a gate-like device control feature.

The CD4516BEG4 counter is used in a wide variety of electronic devices such as remote-controlled toys, power supplies, mechatronic systems, automotive systems, computer peripherals, consumer electronics, military and aerospace applications, and telecommunication systems. CD4516BEG4 consists of several useful and powerful functions, making it a much sought-after and cost-effective solution.
