9.3.4 Additional Options

The SN65HVD17xx family also has options for J1708 applications, for always-enabled full-duplex versions (industry-standard SN65LBC179 footprint) and for inverting-polarity versions, which allow users to correct a reversal of the bus wires without re-wiring. Contact your local Texas Instruments representative for information on these options.
