Part # 74LS74 datasheet

Part Manufacturer: Motorola


Part Description: 74LS74

Part Details:

SN54/74LS74A 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. DUAL D-TYPE POSITIVE Information at input D is transferred to the Q output on the positive-going EDGE-TRIGGERED FLIP-FLOP edge 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-going LOW POWER SCHOTTKY pulse. When the clock input is at either the HIGH or the LOW level, the D inputsignal has no effect.
