7.4.1 Operational Data rate

THVD1400V can be used in slow speed or fast speed RS-485 networks by configuring Slew rate control (SLR) pin. Table 7-3 describes slew rate control function.

Table 7-3 Slew rate control function table
Signal stateDriverReceiverComment
SLR = VIOMaximum speed of operation = 500kbpsMaximum speed of operation = 500kbpsActive high slew rate limiting applied on driver output and glitch filter in receiver path enabled
SLR = GND or floatingMaximum speed of operation = 20Mbps Maximum speed of operation = 20Mbps Slew rate limiting on driver output disabled and glitch filter in receiver path disabled
