D FlipFlop

With Set and Reset

The MC10EL/100EL31 is a D flip-flop with set and reset. The device is

functionally equivalent to the E131 device 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 set and reset inputs are asynchronous, level triggered signals.

Data enters the master portion of the flip-flop when clock is LOW and is

transferred to the slave, and thus the outputs, upon a positive transition of

the clock.
