M74HC4518 is a high-speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2MOS technology. It consist of two identical internally synchronous 4-stage counters.
The M74HC4518 is a high-speed CMOS dual binary counter fabricated with silicon gate CMOS technology. It consists of two identical internally synchronous 4-stage counters, where the counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE inputs for incrementing on either the positive-going or negative-going transition.
The device features a wide operating voltage range from 2V to 6V and is pin and function compatible with the 74 series 4518. It includes protection circuits against static discharge and transient excess voltage. The counters can be cascaded in the ripple mode by connecting Q4 to the enable input of the subsequent counter while the clock input of the latter is held permanently low.
