Description:

Synchronous 4-bit up/down binary counter.

74ACT11191, SYNCHRONOUS 4-BIT UP/DOWN BINARY COUNTER

The 74ACT11191 is a synchronous, 4-bit binary reversible up/down counter.

A synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic.

This mode of operation eliminates the
