TC74AC112P/F
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC112P, TC74AC112F
Dual J-K Flip Flop with Preset and Clear
The TC74AC112 is an advanced high speed CMOS DUAL J-K FLIP FLOP fabricated with silicon gate and double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation.
In accordance with the logic level given J and K input this device changes state on negative going transition of the clock pulse. CLEAR and PRESET are independent of the clock and 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 = 170 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) Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 5.5 V Pin and function compatible with 74F112
