74LS193 Binary Up/Down Counter with Clear

74LS193 Synchronous Binary Up/Down Counter with Clear

The 74LS193 is a versatile synchronous binary up/down counter, part of the popular 74LS series. This modulo-16 counter offers reliable performance for a wide range of digital logic applications. It features separate clock inputs for counting up and down, ensuring precise control. Outputs update synchronously with low-to-high clock transitions, maintaining system integrity. Designed for flexibility, it includes individual preset inputs, allowing for programmable counting sequences. Terminal Count Up and Down outputs simplify the creation of multistage counter systems without additional logic. Both Parallel Load (PL) and Master Reset (MR) inputs provide asynchronous control, overriding clock signals when needed. With high-speed operation up to 25MHz and standard TTL switching voltages, the 74LS193 is an excellent choice for your next project.
