description
The ’HC112 devices contain two independent J-K
negative-edge-triggered flip-flops. 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 are transferred to the
outputs on the negative-going edge of the clock
(CLK) pulse. Clock triggering occurs at a voltage
level and is not directly related to the rise time of
CLK. Following the hold-time interval, data at the
J and K inputs may be changed without affecting
the levels at the outputs. These versatile flip-flops
perform as toggle flip-flops by tying J and K high.
The SN54HC112 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HC112 is characterized for
operation from –40
°C to 85°C.

This configuration is unstable; that is, it does not persist
when either PRE or CLR returns to its inactive (high) level.
