Description
The STLVDS32 is a differential line receiver that
implements the electrical characteristics of low
voltage differential signaling (LVDS). This
signaling technique lowers the output voltage
levels of 5 V differential standard levels (such as
TIA/EIA-422B) to reduce the power, increase the
switching speeds and allow operations with a
3.3 V supply rail. This differential receiver
provides a valid logical output state with a 3.3 V
supply rail. It also provides a valid logical output
state with a ±100 mV differential input voltage
within the input common mode voltage range. The

Package
input common mode voltage allows 1 V of ground
potential difference between two LVDS nodes.
The intended application of this device and
signalling technique is both point-to-point and
multidrop data transmission over controlled
impedance media approximately 100 Ω. The
transmission media may be printed circuit board
traces, backplanes or cables. The ultimate rate
and distance of data transfer depend upon the
attenuation characteristics of the media and noise
coupling to the environment.
The STLVDS32 version is characterized for
operation from -55°C to 125°C.
