About this product
The 74HC191 is a 4-bit synchronous binary up/down counter with asynchronous parallel load. A single up/down input sets the direction, and a count enable input allows cascading multiple counters for longer counts, making it suitable for timers, event counting and frequency division.

How do I change the counting direction?
Use the single up/down control input. On the 74HC191, a LOW level counts up and a HIGH level counts down, so set this pin before the clock edge.
How do I cascade two 74HC191 counters for an 8-bit count?
Connect the ripple clock output (RCO) of the first counter to the clock input of the second, and share the up/down control line between both. The second counter then counts the higher bits.
