– 2000-V Human-Body Model (A114-A)

– 200-V Machine Model (A115-A)

– 1000-V Charged-Device Model (C101)

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.
