SNJ54HC393J - Dual 4-Bit Binary Counter from Texas Instruments

The SNJ54HC393J is a high-performance, dual 4-bit binary counter integrated circuit (IC) manufactured by Texas Instruments (TI). This device belongs to the 54HC family, which is well-known for its robust performance and compatibility with a wide range of digital applications.

Featuring two individual counters in a single package, the SNJ54HC393J provides a practical solution for counting applications. Each counter has a divide-by-two section and a divide-by-eight section, which can be connected to operate either as a divide-by-two counter or as a binary counter for applications requiring up to 8-bit binary counting.

The IC operates over a broad voltage range from 2V to 6V and offers the advantage of high noise immunity characteristic of CMOS devices. Its design ensures low power consumption, making it suitable for battery-operated devices. The SNJ54HC393J is also characterized by a wide operating temperature range, making it ideal for industrial and military-grade applications where reliability under extreme conditions is a necessity.

Each counter advances on the falling edge of the clock signal, providing precise control and synchronization of counting operations. The clear function is asynchronous, which means it can be initiated regardless of the clock input and provides an immediate reset of the counter to its zero state when activated.

Packaged in a durable ceramic dual in-line package (CDIP), the SNJ54HC393J ensures reliable performance even in harsh environments. Its pin configuration is designed to facilitate easy integration into existing systems, as well as for use in new designs.

Whether you're working on timing circuits, frequency dividers, or other digital systems requiring a reliable counting solution, the SNJ54HC393J from Texas Instruments is a versatile and robust choice. With TI's reputation for quality and durability, this IC stands out as a dependable component for your most demanding applications.
