Dual J-K Flip-Flop with Preset and Clear
The TC74HC109A is a high speed
CMOS J- K FLIP FLOP fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the
CMOS low power dissipation.
In accordance with the logic levels applied to the J and K inputs, the outputs change state on the positive going transition of the clock pulse.
CLR and PR are independent of the clock and are accomplished by a low logic level on the corresponding input.
All inputs are equipped with protection circuits against static discharge or transient excess
voltage.
Features
High speed: fmax = 63 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 2 μA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Output drive capability: 10 LSTTL loads Symmetrical output impedance: |IOH| = IOL = 4 mA (min) Balanced p...
