XR3160ECU-F

The XR3160ECU-F is an advanced Multiprotocol Transceiver supporting RS-232, RS-485 and RS-422 serial standards. Full operation requires only four external charge pump capacitors. The RS-485/RS-232 pin selects RS-485 mode when high and RS-232 mode when low. The HALF/FULL pin configures the RS-485 modes as either half or full duplex. The driver can be slew limited to 250kbps in any mode to minimize electromagnetic interference (EMI) by setting the dedicated SLEW pin low. All transmitter outputs and receiver inputs feature robust electrostatic discharge (ESD) protection to ±15kV IEC 61000-4-2 air gap, ±15kV human body model (HBM) and ±8kV IEC 61000-4-2 contact. Each receiver output has full fail-safe protection to avoid system lockup, oscillation or indeterminate states by defaulting to logic-high output level when the inputs are open, shorted or terminated but un-driven. No external biasing resistors are required.
