Description

The SL74HC74 is identical in pinout to the LS/ALS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

This SL74HC74 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.
