TC74AC112P,TC74AC112F,TC74AC112FN
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 C
2
MOS 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.
