TC74HC4060AF
TC74HC4060AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4060AP, TC74HC4060AF 14-Stage Binary Counter/Oscillator The TC74HC4060A is a high speed CMOS 14-STAGE BINARY COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The oscillator configuration allows designs using either RC or crystal oscillator circuits, or an external clock may be used. The clear input resets the counter to a low level on all outputs and disables the oscillator. A high CLR accomplishes this reset function. A negative transition on the clock input ( ϕ I) increments the counter Ten levels of divided output are provided; 4 stage thru 10 stage and 12 stage thru 14 stage. At the last stage (Q14), a 1/16384 divided frequency is obtained. The ϕ I input and CLR input are equipped with protection circuits against static discharge or transient excess voltage.
