Package : DIP, SOP 14 Pin Type
Manufactures : Motorola
Image and Pinout
The SN54/74LS74A dual edge-triggered flip-flop utilizes Schottky TTL circuitryto produce high speed D-type flip-flops. Each flip-flop hasindividual clear and set inputs, and also complementary Q and Qoutputs. Informationat input D is transferred to the Q output on thepositive-going edge of the clock pulse. Clock triggering occursat a voltage level of the clock pulseand is not directly related to the transition time of the positive-going pulse.When the clock input is at either the HIGH or the LOW level, the D input signal has no effect.
