Dual D Flip-Flop with Set and Reset

High-Performance Silicon-Gate CMOS

The SL74HCT74 is identical in pinout to the LS/ALS74. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of two D flip-flops with individual Set, Reset, and Clock inputs. Information at a D-input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip-flop. The Set and Reset inputs are asynchronous.

· TTL/NMOS Compatible Input Levels

· Outputs Directly Interface to CMOS, NMOS, and TTL

· Operating Voltage Range: 4.5 to 5.5 V

· Low Input Current: 1.0 μA
