TEXAS INSTRUMENTS CD74HC93M

The CD74HC93M is a 4bit high speed CMOS binary Ripple Counter pin-compatible with low power Schottky TTL (LSTTL). It consists of four flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has a separate clock input (CP0\ and CP1\) to initiate state changes of the counter on the high to low clock transition. State changes of the Qn outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and should not be used for clocks or strobes.
