3.3 V ECL Differential Clock D Flip‐Flop
MC100LVEL51
Description The MC100LVEL51 is a differential clock D flip-flop with reset. The
device is functionally equivalent to the EL51 device, but operates from a 3.3 V supply. With propagation delays and output transition times essentially equal to the EL51, the LVEL51 is ideally suited for those applications which require the ultimate in AC performance at 3.3 V VCC.
The reset input is an asynchronous, level triggered signal. Data enters the master portion of the flip-flop when the clock is LOW and is transferred to the slave, and thus the outputs, upon a positive transition of the clock. The differential clock inputs of the LVEL51 allow the device to be used as a negative edge triggered flip-flop.
