SEMICONDUCTOR TECHNICAL DATA High-Performance Silicon-Gate CMOS The MC54/74HC74A is identical in pinout to the LS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. 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. * * * * * * Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 128 FETs or 32 Equivalent Gates J SUFFIX CERAMIC PACKAGE CASE 632-08 14 1 N SUFFIX PLASTIC PACKAGE CASE 646-06 14 1 D SUFFIX SOIC PACKAGE CASE 751A-03 14 1 DT SUFFIX TSSOP PACKAGE CASE 948G-01 14 1 ORDERING INFORMATION MC54HCXXAJ MC74HCXXAN MC74HCXXAD MC74HCXXADT Ceramic Plastic SOIC TSSOP LOGIC DIAGRAM PIN ASSIGNMENT RESET 1 DATA 1 CLOCK 1 SET 1 RESET 2 DATA 2 CLOCK 2 SET 2 1 2 5 3 6 Q1 Q1 4 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 13 12 9 11 8 Q2 FUNCTION TABLE Q2 Inputs 10 Outputs Set Reset Clock Data L H L H H H H H PIN 14 = VCC PIN 7 = GND H L L H H H H H X X X L H X X X H L X X X Q Q H L L H H* H* H L L H No Change No Change No Change * Both outputs will remain high as long as Set and Reset are low, but the output states are unpredictable if Set and Reset go high simultaneously. 10/95 Motorola, Inc. 1995 3-1 REV 6 IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII III IIIIIIIIIIIIII IIIIII III IIIIIIIIIIIIIIIIIIIIIII III IIIIIIIIIIIIII IIIIII III IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIII MC54/74HC74A MAXIMUM RATINGS* Symbol VCC Parameter DC Supply Voltage (Referenced to GND) Value Unit - 0.5 to + 7.0 V Vin DC Input Voltage (Referenced to GND) - 1.5 to VCC + 1.5 V Vout DC Output Voltage (Referenced to GND) - 0.5 to VCC + 0.5 V DC Input Current, per Pin 20 mA Iout DC Output Current, per Pin 25 mA ICC DC Supply Current, VCC and GND Pins 50 mA PD Power Dissipation in Still Air, Plastic or Ceramic DIP SOIC Package TSSOP Package 750 500 450 mW Tstg Storage Temperature - 65 to + 150 _C Iin TL This device contains protection circuitry to guard against damage due to high static voltages or electric fields. 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. v v _C Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC or TSSOP Package) (Ceramic DIP) 260 300 * Maximum Ratings are those values beyond which damage to the device may occur.
