AiP74HC191

Asynchronous setting 4-bit synchronous binary up/down counter

AiP74HC191 is a 4-bit binary up/down counter with asynchronous setting and synchronous counting. They include four master/slave flip-flops and internal gate control logic to realize asynchronous setting and synchronous up/down counting functions. Asynchronous parallel data input allows the counter to be preset to any desired value.

AiP74HC192

Asynchronous reset/asynchronous reset BCD up/down counter

AiP74HC192 is an asynchronous reset, asynchronous reset, synchronous BCD up/down counter. With separate up/down clock CPU and CPD, when the rising edge of any clock arrives, the counter counts. Asynchronous parallel data input allows the counter to be preset to any desired value.
