Product Summary

The 74HC74AP is a high speed CMOS D FLIP FLOP fabricated with silicon gate C2MOS technology. The 74HC74AP achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CLOCK pulse. CLEAR and PRESET are independent of the CLOCK and are accomplished by setting the appropriate input to an L level. All inputs of the 74HC74AP are equipped with protection circuits against static discharge or transient excess voltage.

Parametrics

74HC74AP absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 to 7 V; (2)DC input voltage,VIN: -0.5 to VCC + 0.5V; (3)DC output voltage, VOUT: -0.5 to VCC + 0.5V; (4)Input diode current, IIK: ±20 mA; (5)Output diode current, IOK: ±20 mA; (6)DC output current, IOUT: ±25 mA; (7)DC VCC/ground current, ICC: ±50 mA; (8)Power dissipation, PD: 500mW; (9)Storage temperature, Tstg: -65 to 150℃.
