General description

The 74HC393; 7474HCT393 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 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 diodes. This enables the use of
