SEMICONDUCTOR TECHNICAL DATA

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

• >2000V ESD Protection
