1 / 11 page M54HCT74 M74HCT74 February 1993 DUAL D TYPE FLIP FLOP WITH PRESET AND CLEAR B1R (Plastic Package) ORDER CODES : M54HCT74F1R M74HCT74M1R M74HCT74B1R M74HCT74C1R F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) PIN CONNECTIONS (top view) NC = No Internal Connection INPUT AND OUTPUT EQUIVALENT CIRCUIT . HIGH SPEED fMAX = 53 MHz (TYP.) AT VCC =5 V . LOW POWER DISSIPATION ICC =2 µA (MAX.) AT TA =25 °C . COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) . OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE IOH =IOL = 4 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH =tPHL . PIN AND FUNCTION COMPATIBLE WITH 54/74LS74 The M54/74HCT74 is a high speed CMOS DUAL D TYPE FLOP WITH PRESET AND CLEAR fabri- cated in silicon gate C 2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. A signal on the D INPUT is transferred to the Q OUTPUT during the positive going transition of the clock pulse. CLEAR and PRESET are independent of the clock and accomplished by a low on the appropriate input. All inputs are equipped with protection circuits against static discharge and transient excess volt- age. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are de- signed to directly interface HSC 2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
