Product Overview: SN74LS393N Dual 4-Bit Binary Counter

The SN74LS393N is a high-quality integrated circuit produced by Texas Instruments, known for its reliability and precision. This particular model is part of the 74LS logic family, which is a series of low-power Schottky devices. The SN74LS393N is characterized as a dual 4-bit binary counter, which consists of two individual counters in a single package.

Key Features

• Dual 4-Bit Counters: The SN74LS393N contains two independent 4-bit binary counters, each having a clear and a clock input.
• Direct Clearing: Each counter can be cleared directly by a high level on the clear input, ensuring quick initialization or reset.
• Asynchronous Counting: Counting occurs asynchronously, meaning that the output changes state as soon as the clock input changes, without any delay.
• Wide Operating Voltage Range: The device is designed to operate over a wide range of voltages, typically from 4.75V to 5.25V, making it suitable for various applications.
• Low Power Consumption: As a member of the 74LS family, the SN74LS393N boasts low power consumption, which is ideal for power-sensitive designs.
• High-Speed Operation: The counter operates at high speeds, with typical clock frequency capabilities in the megahertz range, allowing for rapid counting and timing operations.

Applications

The SN74LS393N is versatile and can be used in a variety of electronic applications. Its primary function is to count pulses, which can be used in:

• Timing circuits
• Frequency dividers
