74HC191 Presettable synchronous 4-bit binary up/down counter

74HC191 Description

74HC191 Presettable synchronous 4-bit binary up/down counter Rev.7 * 14 March 2024 Product data sheet 1.General .
The 74HC191 is an asynchronously presettable 4-bit binary up/down counter.

74HC191 Features

* Wide supply voltage range from 2.0 to 6.0 V
* CMOS low power dissipation
* High noise immunity
* Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
* CMOS input levels
* Synchronous reversible counting
* Asynchronous parallel lo

74HC191 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-
