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.
