74HC193 Binary Up/Down Counter with Clear IC - DIP-16 Package is a 4-bit synchronous binary up/down counter IC designed for digital counting applications. It provides separate clock inputs for counting up and down, allowing the count direction to be controlled independently. The IC includes asynchronous clear and parallel data inputs for presetting the counter, making it suitable for frequency division, digital counters, sequencing circuits, control systems, and other digital logic applications.
