MC74HCT74A Dual D Flip-Flop with Set and Reset with LSTTL Compatible Inputs High−Performance Silicon−Gate CMOS http://onsemi.com 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.

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 ≤ (Vin or Vout) ≤ 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. Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. †Derating: SOIC Package: –7 mW/_C from 65_ to 125_C RECOMMENDED OPERATING CONDITIONS Symbol VCC Vin, Vout Parameter Min DC Supply Voltage (Referenced to GND) DC Input Voltage, Output Voltage (Referenced to GND) TA Operating Temperature, All Package Types tr, tf Input Rise and Fall Time (Figure 1) Max Unit 4.5 5.5 V 0 VCC V –55 +125 _C 0 500 ns Functional operation above the stresses listed in the Recommended Operating Ranges is not implied.
