SN65MLVD080 - 8-CHANNEL HALF-DUPLEX M-LVDS LINE TRANSCEIVERS

General Description

The SN65MLVD080 and SN65MLVD082 provide eight half-duplex transceivers for transmitting and receiving Multipoint-Low-Voltage Differential Signals in full compliance with the TIA/EIA-899 (M-LVDS) standard, which are optimized to operate at signaling rates up to 250 Mbps.

The driver outputs have been designed to support multipoint buses presenting loads as low as 30-Ω and incorporates controlled transition times to allow for stubs off of the backbone transmission line.

(1) The signaling rate of a line, is the number of voltage transitions that are made per second expressed in the units bps (bits per second).
