... The MAX3465–MAX3469’s driver slew rates allow transmit speeds up to 40Mbps. The MAX3468 and MAX3469 are half-duplex trans- ceivers, while the MAX3465, MAX3466, and MAX3467 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 MAX3467) Low-power shutdown mode is initiated by bringing SHDN high (MAX3465/MAX3466), 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 ...
