The CD74HC393M is a high-performance CMOS dual 4-bit binary counter. It is a dual 4-bit counter that features two separate clock inputs and a common reset input. The CD74HC393M is defined as a logic device (Logic - Counters, Dividers).

The CD74HC393M is a dual 4-bit counter, meaning that it contains two independent 4-bit counter circuits in the same package. Each counter is capable of counting up to sixteen clock pulses, and is reset to zero on the seventeenth pulse. The counter is also programmable so that it can be used as an up/down counter, or as a divide-by-N counter.

The CD74HC393M has two clock inputs, labeled CK1 and CK2. The rising edge of the clock signal determines when the output of the counter changes. The counter also has an active-low reset input, labeled RST, which resets the counter to zero when active.

The output of the CD74HC393M is 4-bit wide, with each bit representing one count. For example, when the counter is at "0011" (binary), the output would be "3" (decimal). The counter is also capable of generating synchronous output, in which the output of the counter remains stable while the clock is low.

The CD74HC393M can be used in a variety of applications, including frequency division, divide-by-N counting, timer/event counter applications, and rate generation. This chip is widely used in industrial and consumer applications such as process control, communication systems, ATMs, POS systems, car alarms, and robotic systems.

In conclusion, the CD74HC393M is a dual 4-bit binary counter with two separate clock inputs and a common reset input. This device can be used in a variety of applications such as frequency division, divide-by-N counting, and rate generation. This chip is widely used in industrial and consumer applications and is a popular choice for designers looking for a reliable and cost-effective solution.
