Overview
19-0453; Rev 0; 1/96 MAX3480A/MAX3480B Complete, Isolated, 3.
3V RS-485/RS-422 Data Interface _______________General Description The MAX3480A/MAX3480B are electrically isolated RS-485/RS-422 data-communications interfaces.
Transceivers, optocouplers, and a transformer are all included in one low-cost, 28-pin DIP package.
A single +3.
3V supply on the logic side powers both sides of the interface.
The MAX3480B features reduced-slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps.
The MAX3480A’s driver slew rate is not limited, allowing transmission rates up to 2.
5Mbps.
These devices typically draw 180mA of quiescent supply current.
The MAX3480B provides a low-power shutdown mode in which it consumes only 0.
2µA.
Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a ...
