SN74HC393DR

The SN74HC393DR is a dual 4-bit binary counter integrated circuit from Texas Instruments, part of the 74HC series, which is known for its high-speed CMOS logic capabilities. It consists of two independent 4-bit binary ripple counters, each with separate clocks and reset inputs. The device is designed for operations with a power supply range of 2V to 6V, making it suitable for a variety of digital applications.
Each counter within the SN74HC393DR comes with four flip-flops, enabling it to count up to 16 (from 0 to 15) before recycling back to zero. The counters are positive-edge triggered, meaning they advance their count on the rising edge of the clock signal. The asynchronous clear function allows the counter to be reset to zero at any time.
This IC is commonly used in digital systems requiring counting, frequency division, or time-delay generation. It is packaged in a small-outline design, which is space-efficient for electronic circuit integration. Due to its low power consumption and wide operating voltage range, it is suitable for battery-operated devices as well.
