General Description

The MAX1482 and MAX1483 are low-power transceivers for RS-485 and RS-422 communication. Both feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps.

Features

♦ Low 20µA Operating Current

♦ Slew-Rate Limited for Reduced EMI and Reduced Reflections

♦ 0.1µA Low-Current Shutdown Mode

♦ Designed for RS-485 and RS-422 Applications

♦ Operate from a Single +5V Supply

♦ -7V to +12V Common-Mode Input Voltage Range

♦ Allows up to 256 Transceivers on the Bus—Guaranteed (1⁄8-unit load)

♦ Current Limiting and Thermal Shutdown for Driver Overload Protection
