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.
Features
High speed: fmax = 62 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 4 μA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Output drive capability: 15 LSTTL loads Symmetrical output impedance: |IOH| = IOL = 6 mA (min) Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 6 V Pin and function compatible with 74LS564/574
