MAX3485AE Datasheet | Maxim Integrated

Description Devices in the MAX3483AE family (MAX3483AE/ MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE) are ±20k V 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. Each transceiver includes a fail-safe receiver, ensuring that the receiver output (RO) is high when inputs are shorted, open, or connected to a three-state bus. All devices feature enhanced electrostatic discharge (ESD) protection. All...
