description

The SN65L VDS1 is a single low-voltage dif feren­tial line driver in the small-outline transistor
package. The outputs comply with the TIA/
EIA-644 standard and provide a minimum
differential output voltage magnitude of 247 mV
into a 100-Ω load at signaling rates up to
630 Mbps.

When used with an LVDS receiver (such as the SN65LVDT2) 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 packaging, low power, low EMI, high ESD tolerance,
and wide supply voltage range make this device ideal for battery-powered applications.

The SN65LVDS1 is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

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 under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential I/O bus voltages are with respect to network ground terminal.
