These dual monolithic J-K flip-flops are negative-edge-triggered. They feature individual J, K, and asynchronous preset inputs to each flip-flop as well as common clock and asynchronous clear inputs. When the clock goes high, the inputs are enabled and data will be accepted. Logical state of J and K inputs may be allowed to change when the clock pulse is in a high state and bistable will perform according to the truth table as long as minimum set-up times are observed. Input data is transferred to the outputs on the negative edge of the clock pulse.
The SN74H108N is characterized for operation over the full military temperature range of 0°C to 70°C.
