TC74HC564AP,TC74HC564AF,TC74HC574AP,TC74HC574AF
Octal D-Type Filp-Flop with 3-State Output TC74HC564AP/AF Inverting TC74HC574AP/AF Non-Inverting
TC74HC564AP, TC74HC574AP
The TC74HC564A and HC574A are high speed CMOS OCTAL FLIP-FLOPs with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These 8-bit D-type flip-flops are controlled by a clock input (CK) and an output enable input ( OE ). The TC74HC564A has inverting outputs, and the TC74HC574A has non-inverting outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW.

Note:
CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPDVCCfIN + ICC/8 (per bit) And the total CPD when n pcs. of flip flop operate can be gained by the following equation: CPD (total) = 39 + 15n
