74FR74
- 74FR1074 Dual D-Type Flip-Flop
General Description
The 74FR74 and 74FR1074 are dual D-type flip-flops with true and plement (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.
Features s 74FR74 is pin-for-pin patible with the 74F74 s True 150 MHz fMAX capability on 74FR74 s Outputs sink 24 mA and source 24 mA s Guaranteed pin-to-pin skew specifications
