MC14516BDR2G is a 4-bit ripple counter chip from the production of ON Semiconductor. It belongs to the Logic family of Counters, Dividers, producing a system that can be used to offer increased speed, accuracy and reliability when counting, dividing or producing multiple outputs.

This integrated circuit is designed to accept a wide range of voltages - from 2V to 18V - and can produce a maximum supply current at 4MHz of 10mA. It is an ideal choice where timing or sequencing is needed, because it offers one extra advantage over other counters. It can counter in the “up” direction of the clock edge, or the “down” direction. It also provides a reset function.

The MC14516BDR2G tries to reduce board space and is not limited to a single unit output. The input and outputs are all solid state, which helps reduce static buildup, broken connections and reduces the overall cost of manufacturing. The chip also has a wide clock input frequency range of up to 20kHz, which can be set by the user.

The MC14516BDR2G provides four different widths for the pulses it generates - 0.6, 1.6, 2.6 and 3.6MHz - and it is capable of counting up to 16 counter cycles. It also provides a maximum of 16 different outputs, which is an important asset when using it in applications such as frequency division. The chip also maintains a high stability over temperatures.

The applications of MC14516BDR2G are diverse, as it can provide the required number of counter cycles in both directions, and can be used in a variety of sequencing applications. It is widely used in a variety of industries, specifically in medical and industrial technologies, such as automation and data gathering.

The MC14516BDR2G works on the ripple counter principle, meaning that it has several unused stages, instead of just one. It is based on the asynchronous counting method, when the bits of the output number change one at a time. Whenever an edge of the detected clock pulse occurs in the input, the data of the cascaded stages changes like a ripple effect.

In other words, the output at each stage depends on the output of the previous stage. In the first stage, the output is the same as the input. By the fourth stage in this chip, it will be half the input frequency, and with further additional stages, it will continue to reduce. When the output of the ripple counter reaches the last stage, the cycle repeats, producing a uniform and repetitive output.

MC14516BDR2G is robust and produces outputs with high repeatability, so it is widely used in many applications. It is also easy to use and install, as it only requires two inputs - the clock and the reset - and four outputs - each driving one of the preset points. This makes it a very versatile choice for many high-speed sequential and control systems.
