High–Performance Silicon–Gate CMOS

The MC74HCT74A is identical in pinout to the LS74. This device may be usedas 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.
