MAX9370/MAX9371/MAX9372 19-2377 Rev 0 4/02 LVTTL/TTL-to-Differential LVPECL/PECL Translators General Description Features The MAX9370/MAX9371/MAX9372 LVTTL/TTL-to-differ- Guaranteed 1GHz Operating Frequency at 600mV ential LVPECL/PECL translators are designed for high- Differential Output speed communication signal and clock driver 270ps Propagation Delay applications. The MAX9370/MAX9372 are dual LVTTL/TTL-to-LVPECL/PECL translators that operate in 10ps Output-to-Output Skew (MAX9370/MAX9372) excess of 1GHz. The MAX9371 is a single translator. Wide Supply Range: 3.0V to 5.25V The MAX9370/MAX9371 operate over a wide 3.0V to 5.25V supply range, allowing high-performance clock (MAX9370/MAX9371) or data distribution in systems with a nominal 3.3V or ESD Protection > 2kV (Human Body Model) 5.0V supply. The MAX9372 is designed to operate from 3.0V to 3.6V. Output High with Input Open The devices default to output high if the input is discon- Available in Small 8-Pin SOT23, MAX, and SO nected. They feature low 270ps propagation delay. The Packages MAX9370/MAX9371/MAX9372 employ industry-stan- Improved Upgrades to MC100EL22, MC100EPT20, dard flow-through pinouts. These devices are specified MC100EPT22 for operation from -40C to +85C, and are offered in space-saving, 8-pin SOT23, MAX, and SO packages.
