Single/Dual LVDS Line Receivers with
Ultra-Low Pulse Skew in SOT23
General Description
The MAX9111/MAX9113 single/dual low-voltage differen-
tial signaling (LVDS) receivers are designed for high-
speed applications requiring minimum power
consumption, space, and noise. Both devices support
switching rates exceeding 500Mbps while operating from
a single +3.3V supply, and feature ultra-low 300ps (max)
pulse skew required for high-resolution imaging applica-
tions such as laser printers and digital copiers.
The MAX9111 is a single LVDS receiver, and the
MAX9113 is a dual LVDS receiver.
Both devices conform to the EIA/TIA-644 LVDS standard
and convert LVDS to LVTTL/CMOS-compatible outputs.
A fail-safe feature sets the outputs high when the inputs
are undriven and open, terminated, or shorted. The
MAX9111/MAX9113 are available in space-saving 8-pin
SOT23 and SO packages. Refer to the MAX9110/
MAX9112 data sheet for single/dual LVDS line drivers.

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.
