description
The SN75LVDS32 and SN75LVDS9637 are
differential line receivers that implement the
electricalcharacteristicsoflow-voltagedifferential
signaling (LVDS). This signaling technique lowers
the output voltage levels of 5-V differential
standard levels (such as EIA/TIA-422B) to reduce
the power, increase the switching speeds, and

allow operation with a 3.3-V supply rail. Any of the four differential receivers provides a valid logical output state
with a ±100 mV allow operation with a differential input voltage within the input common-mode voltage range.
The input common-mode voltage range allows 1 V of ground potential difference between two LVDS nodes.
The intended application of these devices and signaling technique is both point-to-point and multidrop (one
driver and multiple receivers) data transmission over controlled impedance media of approximately 100 Ω. The
transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance
of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the
environment.
The SN75LVDS32 and SN75LVDS9637 are characterized for operation from 0°C to 70°C.
