Hitachi HD74HC112
This device is edge sensitive to the clock input and change state on the negative going transition of the clock pulse.DESCRIPTION
Each flip-flop has independent J, K, preset, clear and clock inputs and Q and Q outputs. Clear and preset are independent of the clock and accomplished by a low logic level on the corresponding input.FEATURES

Q and Q will remain HIGH as long as Preset and Clear are Low, but Q and Q are unpredictable, if Preset and Clear go HIGH simultaneously.
