74192 IC Up/Down Decade Counter
The 74192 IC Up/Down Decade Counter, manufactured by XBLW, is a reliable and efficient component for digital counting systems. This integrated circuit is designed for counting applications that require both up and down counting functionality. It is a 4-bit binary decade counter, ideal for use in systems where accurate counting in both directions is required. The 74192 operates in a range of digital circuits, from simple counting applications to more complex systems like frequency dividers, event counters, and time-based counting tasks.
Features:
- Synchronous reversible counting
