双D型上升沿触发的触发器明确和 DUAL D-TYPE POSITIVE-EDGE-TRIGGERED FLIP-FLOP WITH CLEAR AND
description/ordering information
The SN74HC74 device contains two independent D-type positive-edge-triggered flip-flops. A low level at the preset PRE or clear CLR inputs sets or resets the outputs, regardless of the levels of the other inputs. When PREand CLRare inactive high, data at the data D input meeting the setup time requirements are transferred to the outputs on the positive-going edge of the clock CLK pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of CLK. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs.
