This dual negative-edge-triggered J-K flip-flop is designed for 1.65-V to 3.6-V VCC operation.
A low level at the preset ( PRE) or clear ( CLR) inputs sets or resets the outputs, regardless of the levels of the other inputs. 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. 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 can be changed without affecting the levels at the outputs. The SN74LVC112A can perform as a toggle flip-flop by tying J and K high.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
