ON Semiconductor MM74HC393SJ Dual Binary Counter

The MM74HC393SJ from ON Semiconductor is a high-speed CMOS Dual 4-Bit Binary Ripple Counter designed for use in a wide range of electronic applications requiring reliable counting operations. This integrated circuit is part of the HC family, which ensures compatibility with all CMOS, TTL logic levels, and is fabricated with silicon gate CMOS technology to achieve high-speed operation while maintaining the low power consumption of standard CMOS integrated circuits.

Encased in a slim 14-pin SOIC package, the MM74HC393SJ provides two independent counters, each composed of a 4-bit binary counter with a master reset. The counters advance on the falling edge of the clock signal, offering precise timing and control for sequential operations. The master reset input can override the clock and clear the counter to its zero state, allowing users to reset the counting process at any time, providing flexibility and control over counting sequences.

The versatility of the MM74HC393SJ is further enhanced by its wide operating voltage range of 2V to 6V, making it suitable for interfacing with both standard digital components and newer, low-voltage devices. This feature ensures that the MM74HC393SJ can be integrated into a diverse array of systems without the need for additional level shifting components, simplifying design and reducing costs.

With its fast propagation delay times and low quiescent current, the MM74HC393SJ is an excellent choice for high-speed, low-power applications. It is commonly used in frequency dividers, counters, time-delay circuits, and as part of digital state machines. Its robust design and ON Semiconductor's commitment to quality make the MM74HC393SJ a reliable component for designers and engineers looking to build systems with precise counting capabilities.

Whether you're developing consumer electronics, industrial automation systems, or sophisticated communication devices, the ON Semiconductor MM74HC393SJ Dual Binary Counter offers the performance and reliability needed to meet your counting and timing requirements.
