MAX3480B - RS-485/RS-422 Data Interface

Download the MAX3480B datasheet PDF. This datasheet also covers the MAX3480A variant, as both devices belong to the same rs-485/rs-422 data interface family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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 dissip.
