The MC74AC163DR2G is a Quad Baud Rate Generator, part of the family of Quad Ripple Counters released by ON Semiconductor. These are synchronous 4-bit counter modules, with individual clock inputs and four output Q1, Q2, Q3 and Q4. When the reset line is held low, the output Q is reset, and when the enable line is held low, the clock pulses are ignored. The operating temperature of this series is between -55°C to 125°C.

It is important to note that these baud rate generators\'relatively independent from the overall system clock, and can support very high speed counts of up to 10MHz. With a peak output current of 35mA, the output of the MC74AC163DR2G is able to drive even the most demanding digital systems, including large multiplexers. The counters are ripple counters and are available in 8-pin, 14-pin and 28-pin packages, with a selectable reset delay at power up, 4-bit and 8-bit counters, with individual clock inputs and four output Q1, Q2, Q3 and Q4.

The primary application of the MC74AC163DR2G is as a low-cost synchronous counter and baud rate generator, making it suitable for a range of applications such as LCD controllers, telecommunication and networking, wireless, and medical instruments.

In addition, they can also be used in a range of automation and industrial applications, particularly where space is an issue. These counters offer low power consumption, temperature stability, and a low profile, making them perfect for environments where reliability and accuracy are paramount.

The working principle of the MC74AC163DR2G is quite simple; each count is based on the incoming pulses from the clock input. When the enable line is held low, pulses from the clock are ignored and all outputs remain at the set constant value. When the enable line is high, the counter will sequentially count up or down with each incoming clock pulse.

At each count, the descending output will go from Q1 to Q2 to Q3 to Q4 and lastly Q0. Once the Q0 output is reached, the counter will reset back to the initial output state and continue counting until the reset line is asserted. With the reset line held low, the output will stay in the reset state until the reset line is driven high.

The MC74AC163DR2G is a low-power, temperature stable, accurate and low profile counter, making it ideal for a range of applications. With its fast operating speeds and robust output, it is a useful tool for both precision and cost-savings in systems where accuracy and time-sensitive applications are needed.
