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.

Note 1: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at
TA = +25°C.
Note 2: Current into the device is defined as positive. Current out of the devices is defined as negative. All voltages are referenced
to ground except VTH and VTL.
Note 3: Guaranteed by design, not production tested.
Note 4: AC parameters are guaranteed by design and characterization.
Note 5: CL includes probe and test jig capacitance.
Note 6: fMAX generator output conditions: tR = tF < 1ns (0% to 100%), 50% duty cycle, VOH = 1.3V, VOL = 1.1V.
Note 7: tSKD1 is the magnitude difference of differential propagation delays in a channel. tSKD1 = |tPLHD - tPHLD|.
Note 8: tSKD2 is the magnitude difference of the tPLHD or tPHLD of one channel and the tPLHD or tPHLD of the other channel on the
same device.
Note 9: tSKD3 is the magnitude difference of any differential propagation delays between devices at the same VCC and within 5°C
of each other.
Note 10: tSKD4, is the magnitude difference of any differential propagation delays between devices operating over the rated supply
