The MC100LVEL31 is a D flip-flop with set and reset. The device is functionally equivalent to the EL31 device but operates from a 3.3V supply.With propagation delays and output transition times essentially equivalent to the EL31, the LVEL31 is ideally suited for those applications which require the ultimate in AC performance at low power supply voltages.
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.
