MAX13485EESA+T

RS-422/RS-485 接口 IC Half-Dplx RS-485/422 5V 500ksps LD/Rc

Half-Duplex RS-485/RS-422 Transceivers in μDFN

General Description

The MAX13485EESA+T MAX13485E/MAX13486E +5V, half-duplex, ±15kV ESD-protected RS-485 transceivers feature one driver and one receiver. These devices include fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logichigh if all transmitters on a terminated bus are disabled (high impedance). The MAX13485E/MAX13486E include a hot-swap capability to eliminate false transitions on the bus during power-up or live-insertion.
