MAXIM MAX9159 User Manual
General Description
The MAX9159 dual low-voltage differential signaling
(LVDS) receiver is ideal for applications requiring high
speed, low power, and low noise. The MAX9159 is pin
compatible with the SN65LVDS9637. The MAX9159
conforms to the ANSI TIA/EIA-644 LVDS standard and
converts LVDS to LVTTL-compatible outputs. A fail-safe
feature sets the output high when the inputs are undriven and open, terminated, or shorted. The MAX9159 is
available in an 8-pin SO package and fully specified for
the -40°C to +85°C extended temperature range.
Refer to the MAX9111/MAX9113 data sheet for higher
performance single/dual LVDS line receivers in SOT23
and SO packages. Refer to the MAX9110/MAX9112
data sheet for single/dual LVDS line drivers in SOT23
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.

Note 1: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at T
A
= +25°C.
Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground,
except V
TH
, VTL, and VID.
Note 3: AC parameters are guaranteed by design and characterization.
Note 4: C
L
includes scope probe and test jig capacitance.
Note 5: All input pulses are supplied by a generator having the following characteristics: t
R
or tF≤ 1ns, pulse repetition rate (PRR) =
50Mpps, pulse width = 10 ±0.2ns.
Note 6: t
SK(O)
is the skew between specified outputs of a single device with all driving inputs connected together and the outputs
switching in the same direction while driving identical specified loads.
Note 7: t
SK(PP)
is the magnitude of the difference in propagation delay times between any specified terminals of two devices when
both devices operate with the same supply voltages, same temperature, and have identical packages and test circuits.
