... RS-485/RS-422 Transceivers with Preemphasis for High-Speed, Long-Distance Communication Setting the Preemphasis Interval The MAX3291 has an internal fixed preemphasis interval of 100ns. Use the MAX3291 for existing designs requiring industry-standard ’75180 pin-compatibility at data rates of 5Mbps to 10Mbps. The MAX3292 has a resistor-programmable preemphasis interval for more flexibility. For data rates less than 1Mbps, ...

... Low-Power Shutdown Mode Initiate low-power shutdown mode by bringing RE high and DE low. In shutdown the MAX3291/MAX3292 typi- cally draw only 1µA of supply current. Simultaneously driving RE and DE is allowed; the parts are guaranteed not to enter shutdown high and DE is low for less than 80ns ...

... RS-485/RS-422 levels with 128 receivers, but the preemphasis effect is significantly diminished. The MAX3291/ MAX3292 are centered for a load imped- ance of 54Ω, which corresponds to the parallel combina- tion of the cable impedance and termination resistors. If your cable impedance deviates somewhat from this ...
