Download the CD74HC191 datasheet PDF. This datasheet also covers the CD74HC190 variant, as both devices belong to the same synchronous up/down counters family and are provided as variant models within a single manufacturer datasheet.
The CD54/74HC190 are asynchronously presettable BCD decade counters, whereas the CD54/74HC191 and CD54/74HCT191 are asynchronously presettable binary counters.
D) is accomplished by a low asynchronous parallel
