Part Number : 74LS74A
Function : DUAL D-TYPE POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH PRESET AND CLEAR
Package : DIP 14, SOIC 14 Pin Type
Maker : Motorola , Freescale
Pinouts :
Description :
TheSN54LS74A / 74LS74A dual edge-triggered flip-flop utilizesSchottky 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 edgeof 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.
