description
The SN65LVDM1676 and SN65LVDM1677
(integrated termination) are sixteen differential
line drivers and receivers configured as trans-
ceivers that use low-voltage differential signaling
(LVDS) to achieve signaling rates in excess of
600 Mbps. These products are similar to
TIA/EIA-644 standard compliant devices
(SN65LVDS) counterparts except that the output

current of the drivers are doubled. This modification provides a minimum differential output voltage magnitude
of 247 mV into a 50-Ω load and allows double-terminated lines and half-duplex operation. The receivers detect
a voltage difference of 100 mV with up to 1 V of ground potential difference between a transmitter and receiver.
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.
