Function Table
The SN65LVDS2 is a single low-voltage differen-
tial line receiver in a small-outline transistor
package. The inputs comply with the TIA/EIA-644
standard and provide a maximum differential input
threshold of 100 mV over an input common-mode
voltage range of 0 V to 2.4 V.

or clocking signals can be transmitted over printed-circuit board traces or cables at very high rates with very
low electromagnetic emissions and power consumption.
The high-speed switching of LVDS signals requires the use of a line impedance matching resistor at the
receiving-end of the cable or transmission media. TI offers you both the SN65LVDS2, which requires this
external resistor, or its companion the SN65LVDT2, which eliminates the need by integrating it with the receiver.
The packaging, low power, low EMI, high ESD tolerance, and wide supply voltage range make these devices
ideal for battery-powered applications.
The SN65LVDS2 is characterized for operation from –40°C to 85°C.
