MC100LVEL51/D
MC100LVEL51
3.3V ECL Differential Clock
D Flip‐Flop
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 V
CC
.
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.
The differential input employs clamp circuitry to maintain stability
under open input conditions. When left open, the CLK input will be
pulled down to V
EE
and the CLK input will be biased at V
CC
/2.
