D FlipĆFlop
With Set and Reset
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 (or
+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.
• 475ps Propagation Delay
• 2.9GHz Toggle Frequency
• 75kΩ Internal Input Pulldown Resistors
