SN74LS74N - DUAL D-TYPE POSITIVEEDGE-TRIGGERED FLIP-FLOP

The SN54/ 74LS74A dual edge-triggered flip-flop utilizes Schottky TTL cir-cuitry to produce high speed D-type flip-flops. Each flip-flop has individualclear and set inputs, and also complementary Q and Q outputs.Information at input D is transferred to the Q output on the positive-goingedge of the clock pulse. Clock triggering occurs at a voltage level of the clockpulse and is not directly related to the transition time of the positive-goingpulse. When the clock input is at either the HIGH or the LOW level, the D inputsignal has no effect
