The SN65LVDS179, SN65LVDS180, SN65LVDS050, and SN65LVDS051 devices are differential line
drivers and receivers that use low-voltage differential signaling (LVDS) to achieve signaling rates
as high as 400 Mbps. The TIA/EIA-644 standard-compliant electrical interface provides a minimum
differential output voltage magnitude of 247 mV into a 100-Ω load and receipt of 100-mV signals
with up to 1 V of ground potential difference between a transmitter and receiver.
These devices offer various driver, receiver, and enabling combinations in
industry-standard footprints. Because these devices are intended for use in simplex or distributed
simplex bus structures, the driver enable function does not put the differential outputs into a
high-impedance state but rather disconnects the input and reduces the quiescent power used by the
device. For these functions with a high-impedance driver output, see the SN65LVDM series of
devices. All devices are characterized for operation from –40°C to 85°C.
