The MAX14781E +5V, half-duplex ±25kV ESD-protected RS-485 transceiver features integrated automatic polarity correction to ensure that miswired A and B lines are autonomously corrected, simplifying equipment and network installation. The MAX14781E includes slew-rate limited drivers that minimize EMI, allowing for error-free data transmission up to 370kbps. This device includes fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are shorted or open. Hot-swap functionality on the receiver and driver enable inputs also eliminates false transitions on the bus during power-up or live insertion. The MAX14781E features a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. All driver outputs are protected up to ±25kV ESD using the Human Body Model. The MAX14781E is available in an 8-pin SO package and operates over the extended -40°C to +85°C temperature range.
