MC74HCT74A Dual D Flip-Flop with Set and Reset with LSTTL Compatible Inputs High-Performance Silicon-Gate CMOS The MC74HCT74A is identical in pinout to the LS74. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device consists of two D flip-flops with individual Set, Reset, and Clock inputs. Information at a D-input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip-flop. The Set and Reset inputs are asynchronous. http://onsemi.com MARKING DIAGRAMS 14 PDIP-14 N SUFFIX CASE 646 14 1 1 Features * * * * * * * * MC74HCT74AN AWLYYWWG 14 Output Drive Capability: 10 LSTTL Loads TTL NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 mA In Compliance With the JEDEC Standard No. 7.0 A Requirements Chip Complexity: 136 FETs or 34 Equivalent Gates Pb-Free Packages are Available 1 DATA 1 CLOCK 1 SET 1 RESET 2 DATA 2 CLOCK 2 A L, WL Y, YY W, WW G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package PIN ASSIGNMENT 1 2 5 3 6 Q1 RESET 1 1 14 VCC DATA 1 2 13 RESET 2 CLOCK 1 3 12 DATA 2 SET 1 4 11 CLOCK 2 Q1 5 10 SET 2 Q1 6 9 Q2 GND 7 8 Q2 Q1 4 13 PIN 14 = VCC PIN 7 = GND 12 9 11 8 FUNCTION TABLE Inputs Q2 Q2 10 Design Criteria Value Units Internal Gate Count 34 ea.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. _C 260 Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
