CD74HC93 高速 CMOS 逻辑 4 位二进制纹波计数器

The CD74HC93 and CD74HCT93 are high-speed silicon-gate CMOS devices and are pin-compatible with low power Schottky TTL (LSTTL). These 4-bit binary ripple counters consist of four master-slave 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.

A gated AND asynchronous master reset (MR1 and MR2 is provided which overrides both clocks and resets (clears) all flip-flops
