DESCRIPTION
Information at the input is transferred to the outputs on the positive edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. After the Clock Pulse input threshold voltage has been passed, the Data input is locked out and information present will not be transferred to the outputs until the next rising edge of the Clock Pulse input.FEATURES
Asynchronous Inputs: Low input to SD (Set) sets Q to High level Low input to CD (Clear) sets Q to Low level Clear and Set are independent of clock Simultaneous Low on CD and SD makes both Q and Q High● Outputs Source/Sink 24 mA HD74AC74 Pin Arrangement CD1 1 D1 2 CP1 3 SD1 4 Q1 5 Q1 6 GND 7 (Top view) D2 CD2 CP2 SD2 CP1 D1 SD1 CD1 14 VCC 13 CD2 12 D2 11 CP2 10 SD2 9 Q2 8 Q2 Q 1 Q1 Q 2 Q2 Logic Symbol SD1 D1 CP1 Q1 Q1 D2 SD2 Q2 CP2 Q2 CD1 CD2 Pin Names D1, D2 CP1, CP2 C D1, CD2 S D1, SD2 Q1, Q1, Q2, Q 2 Data Inputs Clock Pulse...
