SEMICONDUCTOR TECHNICAL DATA
D Flip Flop
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.
