Description: Presettable synchronous BCD decade up/down counter

Features

* Synchronous reversible counting
* Asynchronous parallel load
* Count enable control for synchronous expansion
* Single up/down control input
* Output capability: standard

Applications

* Fig.6 shows a method of causing state changes to occur simultaneously in all stages. The RC outputs propagate the carry/borrow signals in ripple fashion and all clock inputs are driven in parallel. In this configuration the duration of the clock LOW state must be long enough to allow the negative-g
