The devices support a wide common-mode input range of 0.05V to 2.35V, allowing for ground potential differences and common-mode noise between the driver and the receiver. A fail-safe feature sets the output high when the inputs are open, or when the inputs are undriven and shorted or parallel terminated. The EN and EN inputs control the high-impedance output. The enables are common to all four receivers. Inputs conform to the ANSI TIA/EIA644 LVDS standard. Flow-through pinout simplifies PC board layout and reduces crosstalk by separating the LVDS inputs and LVCMOS outputs. The MAX9121/ MAX9122 operate from a single +3.3V supply, and are specified for operation from -40C to +85C. These devices are available in 16-pin TSSOP and SO packages. Refer to the MAX9123 data sheet for a quad LVDS line driver with flow-through pinout.
