description
The SN65LVDT2 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 2.5 V.

When used with a low-voltage differential

signaling (LVDS) driver (such as the SN65LVDS1)
in a point-to-point connection, data 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 both the SN65LVDT2, which integrates the
terminating resistor for point-to-point applications, and its companion the SN65LVDS2, which requires an
external resistor. The packaging, low power, low EMI, high ESD tolerance, and wide supply voltage range make
these devices ideal for battery-powered applications.
The SN65LVDT2 is characterized for operation from –40°C to 85°C.
