ON Semiconductor DM74LS393MX Dual 4-Stage Binary Counter

The DM74LS393MX from ON Semiconductor is a high-performance, dual 4-stage binary counter integrated circuit. This device is part of the 74LS series and is designed to operate with exceptional reliability and speed, making it an ideal choice for a wide range of counting applications in various electronic systems.

Constructed using low-power Schottky technology, the DM74LS393MX offers a significant advantage in power consumption, which is crucial for battery-operated and energy-efficient devices. Each counter features a fully independent clock circuit, allowing the two counters to operate completely separately from one another. This flexibility makes it possible to use the counters in various configurations, such as divide-by-n counters, frequency dividers, or in applications requiring two unrelated counting operations.

The binary counters are edge-triggered and count on the positive-going transition of the clock inputs. This precise triggering ensures accurate counting and timing operations. The clear function is asynchronous, meaning that it can reset the counter to zero at any time, regardless of the clock input, providing a convenient method for resetting the system during operation or initialization.

The DM74LS393MX is provided in a compact SOIC-14 package, which is suitable for surface-mount technology (SMT) and helps to conserve space on printed circuit boards (PCBs). This packaging, combined with the device's low power requirements and high-speed operation, makes it an excellent choice for portable electronics, digital systems, and instrumentation applications.

ON Semiconductor's commitment to quality ensures that the DM74LS393MX meets the stringent requirements for industrial and commercial use. The device is characterized for operation from 0°C to 70°C, providing a reliable performance across a wide range of environmental conditions.

In summary, the DM74LS393MX dual 4-stage binary counter from ON Semiconductor is a versatile and efficient component for designers who require a dependable and low-power solution for their counting and timing needs in electronic circuits.
