DESCRIPTION
The SY55852U is a flip-flop used to synchronize data
to a clock. Its differential output will reproduce and
remember the value on its input at the rising edge of the
clock. In addition, an asynchronous, level sensitive reset
is provided. For a synchonous reset, the SY55851U
AnyGate™ can be used.
SY55852U inputs can be terminated with a single
resistor between the true and complement pins of a given
input.
The SY55852U is a member of Micrel's SuperLite™
family of high-speed CML logic. This family features very
small packaging and 2.3V to 5.7V operation.
APPLICATIONS
