Datasheet
The MAX9179 is a quad low-voltage differential
signaling (LVDS) line receiver designed for applications
requiring high data rates, low power dissipation, and
noise immunity. The receiver accepts four LVDS input
signals and translates them to 3.3V LVCMOS output lev-
els at speeds up to 400Mbps. The receiver features
built-in hysteresis, which improves noise immunity and
prevents multiple switching on slow transitioning inputs.
The device supports a wide 0.038V to 2.362V common-
mode input voltage range, allowing for ground potential
differences and common-mode noise between the driver
and the receiver. A fail-safe circuit sets the output high
when the input is open, undriven and shorted, or undriven
and terminated. Common enable inputs control the high-
impedance outputs.
The MAX9179 has a flow-through pinout for easy PC
board layout, and is pin compatible with the MAX9121
and the DS90LV048A with the additional features of
high ESD tolerance and built-in hysteresis.
The MAX9179 operates from a single 3.3V supply, and is
specified for operation from -40°C to +85°C. The device
is offered in 16-pin TSSOP and thin QFN packages.
