Overview The 74HC393; 74HCT393 is a dual 4-stage binary ripple counter. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ. a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP. Inputs include clamp .

ManufacturerTexas Instruments
Overview ordering information The ’HC393 devices contain eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. These devices comprise two independent 4-bit bina. put. N-bit binary counters can be implemented with each package, providing the capability of divide by 256. The ’HC393 devices have parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals. 1QA NC 1QB NC 1QC 3 2 1 20 19 4.
