Description
The 74HC393 is a dual 4-bit 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 current-limiting resistors to interface inputs to voltages in excess of VCC.
