| Title | 4-BIT SYNCHRONOUS UP/DOWN BINARY COUNTERS |
| Description | ordering information The ’HC191 devices are 4-bit synchronous, reversible, up/down binary counters. Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the steering logic. This mode of ope. |
| Features | a fully independent clock circuit. Change at the control (CTEN and D/U) inputs that modifies the operating mode have no effect on the contents of the counter until clocking occurs. The function of the counter is dictated solely by the condition meeting the stable setup and hold times. These counters are fully programmable; that is, each of the outputs can be preset to either level by placing a low. |
