Texas Instruments 74F112
The SN74F112 contains two independent J-K negative-edge-triggered flip-flops. When PRE and CLR are inactive (high), data at the J and K inputs meeting the setup time requirements is transferred to the outputs on the negative-going edge of the clock pulse.| Part No. | 74F112 |

SN74F112 DUAL NEGATIVE-EDGE-TRIGGERED J-K FLIP-FLOP WITH CLEAR AND PRESET SDFS048A – D2932, MARCH 1987 – REVISED OCTOBER 1993
● Package Options Include Plastic Small-Outline Packages and Standard Plastic 300-mil DIPs description A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs regardless of the levels of the other inputs. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. The SN74F112 can perform as a toggle flip-flop by tying J and K high.
