General Description

The MAX9370/MAX9371/MAX9372 LVTTL/TTL-to-differ-

ential LVPECL/PECL translators are designed for high-

speed communication signal and clock driver

applications. The MAX9370/MAX9372 are dual

LVTTL/TTL-to-LVPECL/PECL translators that operate in

excess of 1GHz. The MAX9371 is a single translator.

The MAX9370/MAX9371 operate over a wide 3.0V to

5.25V supply range, allowing high-performance clock

or data distribution in systems with a nominal 3.3V or

5.0V supply. The MAX9372 is designed to operate from

3.0V to 3.6V.

The devices default to output high if the input is discon-

nected. They feature low 270ps propagation delay. The

MAX9370/MAX9371/MAX9372 employ industry-stan-

dard flow-through pinouts. These devices are specified

for operation from -40°C to +85°C, and are offered in

space-saving, 8-pin SOT23, µMAX, and SO packages.
