74HC393DB: Dual 4-bit binary ripple counter
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 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.
