74FR74 • 74FR1074
Dual D-Type Flip-Flop
General Description
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 nega-
tive edge triggered version of this device. Both parts fea-
ture asynchronous clear (CDn) and set (SDn) inputs which
are low level enabled.
Features
s 74FR74 is pin-for-pin compatible 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
