ON Semiconductor 74F193SC: 4-Bit Binary Up/Down Counter
The 74F193SC from ON Semiconductor is a high-performance, 4-bit binary up/down counter with a versatile design that allows for a wide range of counting applications. This integrated circuit is designed for use in sophisticated control systems, instrumentation, and processor systems where reliable and fast counting operations are required. The counter features a synchronous reversible operation on the 4-bit binary count and offers the user the ability to count both up and down depending on the mode selected.
Constructed with advanced silicon-gate BiCMOS technology, the 74F193SC provides a robust solution with low power consumption and high noise immunity, making it suitable for operation in harsh industrial environments. Its operating voltage ranges from 4.5V to 5.5V, which is ideal for standard TTL logic levels, ensuring compatibility with a wide array of digital systems.
The device includes key functional elements such as a clear (CLR) input, which resets the counter to its zero state, and count-up (CU) and count-down (CD) inputs for controlling the counting direction. The counter advances one count on the positive-going transition of the clock when the CU input is held high and the CD input is held low. Conversely, it decrements the count on the positive-going clock transition when the CD input is held high and the CU input is low. The output is available in a 4-bit binary format, which can be easily interfaced with other digital components.
Additional features of the 74F193SC include a fully synchronous internal architecture, which minimizes counting errors and ensures reliable operation at high speeds. It also provides both ripple-carry (RCO) and borrow (BOR) outputs, which can be used for cascading multiple counters for extended counting ranges without additional gating.
Manufactured in a compact 16-pin SOIC package, the 74F193SC is designed for space-constrained applications while still offering the robustness and precision expected from ON Semiconductor products. Whether used in counters, dividers, or as part of a more complex digital system, the 74F193SC is a versatile and reliable choice for designers seeking performance and dependability.
Please note: The 74F193SC is a product of ON Semiconductor, and its specifications and uses should be verified with the latest datasheets and application notes from the manufacturer to ensure correct integration into your design.
