Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9401/MAX9404 are extremely fast and lowskew quad ECL/PECL differential buffers/receivers for data and clock signals. The four channels can be operated synchronously with an external clock, or in asynchronous mode, determined by the state of the SEL input. An enable input of MAX9401 provides the ability to force all the outputs to a differential low state.

The MAX9401 has high-impedance (open) input and the MAX9404 has an integrated 100 differential input termination, which reduces external component count.

Both devices have double amplitude swing open emitter outputs suitable for driving long cables. The MAX9401/MAX9404 operate over a V_CC - V_EE = +3.0V to +5.5V supply range, and are specified for operation from -40 to +85. These devices are offered in space-saving 32-pin 5mm x 5mm QFN exposed-paddle (EP) and TQFP packages.
