高速 CMOS 逻辑 12 级二进制计数器
The HC4040 and HCT4040 are 14-stage ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of the stage advances one count on the negative clock transition of each input pulse; a high voltage level on the MR line resets all counters to their zero state. All inputs and outputs are buffered.
\- Standard Outputs...10 LSTTL Loads
