The SY10/100EL31 are D flip-flops with set and reset.
The devices are functionally equivalent to the E131
devices, with higher performance capabilities. With
propagation delays and output transition times
significantly faster than the E131, the EL31 is ideally
suited for those applications which require the ultimate
in AC performance.
Both the set and reset inputs are asynchronous, level
triggered signals. Data enters the master portion of the
flip-flop when the clock is LOW and is transferred to the
slave, and thus the outputs, upon a positive transition of
the clock.
