MAX483EEPA [Maxim]

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. They feature ±15kV ESD protection, slew-rate limiting for some models to minimize EMI and reflections, and low power consumption with supply current as low as 120µA and shutdown current of 0.5µA. All parts operate from a single +5V supply. Drivers are short-circuit current limited with thermal shutdown, and receivers have fail-safe features. The MAX487E and MAX1487E have quarter-unit-load receiver input impedance, allowing up to 128 transceivers on the bus. The MAX488E–MAX491E are full-duplex, while others are half-duplex.
