max

s 2.3V to 5.7V power supply

s Single bit latch

s Stores or flows through 1 bit of data

s Optimized to work with SuperLite™ family

s Fully differential

s Source terminated CML outputs for fast edge rates

s Accepts CML, PECL, LVPECL input logic levels

The SY55853U is a latch. Its differential output will

flow through the input while it's enable is high. The output

will remain static while the enable is low. In addition, an

asynchronous, level sensitive reset is provided.

SY55853U inputs can be terminated with a single

resistor between the true and the complement pins of a

given input.

The SY55853U 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.
