description

The SN75LVDS32 and SN75LVDS9637 are

differential line receivers that implement 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 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.
