Analog Devices / Maxim Integrated MAX9394 2:1 Multiplexer & 1:2 Demultiplexer
Analog Devices Inc. MAX9394 2:1 Multiplexer and 1:2 Demultiplexer consists of a 2:1 multiplexer and a 1:2 demultiplexer with loopback that is guaranteed to operate at 1.35GHz fMAX. The multiplexer section (channel B) accepts two low-voltage differential signaling (LVDS) inputs and generates a single LVDS output. The demultiplexer section (channel A) accepts a single LVDS input and generates two parallel LVDS outputs. This device features a loopback mode that connects the input of channel A to the output of channel B and connects the selected input of channel B to the outputs of channel A. LVDS inputs and outputs are compatible with the TIA/EIA-644 LVDS standard. The LVDS outputs drive 100Ω loads. This devices is offered in a 32-pin TQFP package and operates over the extended temperature range (-40°C to +85°C).
