description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the Preset or Clear inputs sets or resets the
outputs regardless of the levels of the other inputs.
When Preset and Clear 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 pulse. Clock
triggering occurs at a voltage level and is not
directly related to the fall 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. These versatile flip-flops can
perform as toggle flip-flops by tying J and K high.
The SN54ALS114A is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74ALS114A is characterized for
operation from 0
°C to 70°C.

The output levels in this configuration are not guaranteed to
meet the minimum levels for VOH if the lows at Preset and
Clear are near VIL maximum. Furthermore, this configuration
is nonstable; that is, it will not persist when either Preset or
Clear returns to its inactive (high) level.
