The MAX9380 is a high-speed, low-jitter 2:1 multiplexer for clock and data distribution applications. The device selects one of the two single-ended inputs and converts it to a differential output. The MAX9380 features low part-to-part skew of 33ps and propagation delay of 263ps. The MAX9380 operates from a +3.0V to +3.8V supply for LVPECL applications or from a -3.0V to -3.8V supply for LVECL applications. The input is selected by a single select input. The select and data inputs feature internal pulldown resistors that ensure a low default state if left open. These devices are specified for operation from -40C to +85C, and are available in space-saving 8-pin MAX and SO packages.
