SN75C185DW Frequently Asked Questions (FAQs)

  • The SN75C185DW can support data rates up to 100 Mbps.
  • Yes, the SN75C185DW can be used in a multi-point bus configuration, but it requires an external bias resistor to ensure proper operation.
  • To ensure reliable operation in a noisy environment, it is recommended to use a shielded cable, keep the cable length as short as possible, and use a common-mode choke or ferrite bead to filter out electromagnetic interference (EMI).
  • The maximum cable length that can be used with the SN75C185DW depends on the data rate and the type of cable used. As a general rule, the cable length should not exceed 10 meters at a data rate of 100 Mbps.
  • The SN75C185DW can be used in either a half-duplex or full-duplex configuration, depending on the application requirements.
