The M74HC592 is a high speed CMOS 8-bit register counter fabricated with silicon gate C2MOS technology. The M74HC592 is a parallel input, 8 bit storage register feeding an 8 bit binary counter. Both the register and the counter have individual positive edge triggered clock. In addition, the counter has direct load and clear functions. Expansion is easily accomplished by connecting RCO at the first stage to the count enable of the second stage. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
