... DS2119ME 5 DS2119ME+ 5 DS2119ME/T&R 5 DS2119ME+T& Denotes a lead-free/RoHS-compliant package. * The top mark includes a "+" on lead-free packages. DETAILED DESCRIPTION The DS2119M Ultra3 LVD/SE SCSI terminator is both a low-voltage differential (LVD) and single- ended (SE) terminator. The multimode operation enables the designer to implement LVD in current products while allowing the end-user SE-backward compatibility with legacy devices. If the device is connected in an LVD-only bus, the DS2119M will use LVD termination ...
