The 74FR74 and 74FR1074 are dual D-type flip-flops with true and complement (Q/Q) outputs. On the 74FR74, data at the D inputs is transferred to the outputs on the rising edge of the clock input (CPn). The 74FR1074 is the negative edge triggered version of this device. Both parts feature asynchronous clear (CDn) and set (SDn) inputs which are low level enabled.
