(TOP VIEW) DESCRIPTION
The SN55LVDS32 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 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 В±100-mV
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 …
