MAX3483AE - 20Mbps and Slew-Rate-Limited RS-485/RS-422 Transceivers

General Description

Devices in the MAX3483AE family (MAX3483AE/ MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE) are ±20kV ESD-protected RS-485/422 transceivers, optimized for extended cable runs in noisy environments.

All devices operate from a single 3.3V supply.

The MAX3483AE and MAX3485AE are half-duplex transceivers.

MAX3483AE/MAX3485AE/ MAX3488AE/MAX3490AE/ MAX3491AE +3.3V-Powered, ±20kV ESD-Protected, 20Mbps and Slew-Rate-Limited RS-485/RS-422 Transceivers General Description Devices in the MAX3483AE family (MAX3483AE/ MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE) are ±20kV ESD-protected RS-485/422 transceivers, optimized for extended cable runs in noisy environments. All devices operate from a single 3.3V supply. The MAX3483AE and MAX3485AE are half-duplex transceivers. The MAX3488AE, MAX3490AE, and MAX3491AE are full-duplex transceivers. The MAX3483AE/85AE have a 1-unit load receiver input impedance, allowing up to 32 transceivers on the bus. The MAX3488AE/90AE/91AE have a 1/4-unit load receiver input impedance, allowing up to 128 transceivers on the bus.
