DESCRIPTION/ORDERING INFORMATION
This dual negative-edge-triggered J-K flip-flop is designed for 1.65-V to 3.6-V V
CC
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.

DUAL NEGATIVE-EDGE-TRIGGERED J-K FLIP-FLOP
WITH CLEAR AND PRESET
SCAS289L–JANUARY 1993–REVISED AUGUST 2005
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.
