Description
74192 Up/Down Decade Counter 5V 8mA IC DIP-16
The 74192 (SN74LS192) is a presettable BCD decade counter designed for synchronous up and down counting operations. It accepts separate clock inputs for counting up and counting down, allowing precise control over count direction. The IC counts in BCD (0 to 9) and then rolls over, making it ideal for decimal-based digital systems.
This counter features asynchronous master reset and parallel load inputs, enabling fast initialization and programmable starting values. It also includes terminal count outputs for cascading multiple counters, simplifying the design of multi-digit counting systems such as digital clocks and frequency counters.
