LVTTL/TTL-to-Differential LVPECL/PECL
Translators
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.

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.
DC ELECTRICAL CHARACTERISTICS
(VCC = 3.0V to 5.25V for MAX9370/MAX9371, VCC = 3.0V to 3.6V for MAX9372, outputs terminated with 50±1% to VCC - 2.0V.
Typical values are at VCC = 3.3V, VIH = 2.4V, VIL = 0.4V, unless otherwise noted.) (Notes 1, 2, 3)
