ON Semiconductor DM74LS393N Dual 4-Bit Binary Counter

The DM74LS393N from ON Semiconductor is a high-performance, dual 4-bit binary counter integrated circuit, designed for use in a wide array of electronic applications requiring reliable and precise counting operations. Encased in a durable 14-pin plastic DIP (Dual In-line Package), this device is a testament to ON Semiconductor's commitment to providing robust and efficient solutions for digital systems.

This precision counter features two individual 4-bit counters in a single package, allowing for compact and efficient use of circuit board space. Each counter is fully independent and can be operated in a synchronous mode, ensuring accurate and simultaneous operations. The DM74LS393N operates on a power supply range of 4.75V to 5.25V, making it suitable for TTL (Transistor-Transistor Logic) environments.

One of the key attributes of the DM74LS393N is its high-speed performance. The device is capable of handling fast count operations, which is essential for applications that require quick data processing and timing control. Furthermore, the counters can be easily cascaded by feeding the ripple carry output to the enable input of the subsequent counter, allowing for the creation of larger counting sequences without the need for additional external circuitry.

The DM74LS393N is designed with ease of use in mind. It features direct clear inputs to reset the counter to its zero state, and the outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance variations. This makes the device an excellent choice for use in noisy environments where signal integrity is paramount.

Typical applications for the DM74LS393N include time delay circuits, frequency dividers, counters, and clocks. Its robust design and versatility make it an ideal component for designers looking to implement reliable timing and counting solutions in their digital systems. Whether it's for industrial control systems, consumer electronics, or educational projects, the DM74LS393N offers a practical and cost-effective solution that upholds the quality standards of ON Semiconductor.
