SN74HC174数据手册集成电路（IC）的触发器规格书PDF

描述 Description

These positive-edge-triggered D-type flip-flops have a direct clear (CLR)\\ input.

Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going edge of CLK. When CLK is at either the high or low level, the D input has no effect at the output.
