Product Details

The 74HC393N consists of two 4-bit binary ripple counters with individual clock inputs. These counters are designed for asynchronous reset rather than synchronous load capability, providing a simpler design and saving on hardware costs. Each counter has a divide-by-two section and a divide-by-eight section, which can be used separately or combined to count in binary for a full 4-bit division.

The device features a wide operating voltage range from 2V to 6V, making it suitable for battery-operated applications. It also has the ability to drive 15 LSTTL loads, which is substantial for various logic-level conversions and interfacing. The 74HC393N can operate in a broad temperature range from -40°C to +125°C, ensuring reliability and performance under extreme conditions.

Applications

Due to its versatility, the 74HC393N is widely used in a variety of applications including:

• Time delay circuits
• Counter circuits in digital clocks and watches
• Frequency division applications
• General digital logic applications

With its robust design and wide applicability, the 74HC393N from NXP is a staple component for designers and engineers looking for a reliable and efficient binary ripple counter solution.
