... ST75185CN standards. These standards are interchange between a host computer and peripheral at signalling rates up to 20k-bits/s. The switching speeds of the ST75185 are fast enough DB9S to support rates up to 120K-bits/s with lower capacitive loads (shorter cables). Interoperability at the higher signalling rates cannot be assured unless the designer has design control of the cable and the interface circuits at the both ends ...
