... The MAX3460–MAX3464’s driver slew rates allow transmit speeds up to 20Mbps. The MAX3463 and MAX3464 are half-duplex trans- ceivers, while the MAX3460, MAX3461, and MAX3462 are full-duplex transceivers. All of these parts operate from a single +5V supply. Drivers are output short-cir- cuit current limited ...

... RS-485 transceivers with a total of 32 unit loads or less can be connected to the line. Low-Power Shutdown Mode (except MAX3462) Low-power shutdown mode is initiated by bringing SHDN high (MAX3460/MAX3461), or both RE high and DE low. In shutdown, the devices typically draw only 1µA of supply current. RE and DE can be driven simul- taneously ...
