XR3160E RS-232/RS-485/RS-422 Transceivers & Eval Board

Exar XR3160E RS-232/RS-485/RS-422 Transceivers are advanced multiprotocol transceivers with 15KV ESD protection. All transmitter outputs and receiver inputs provide robust electrostatic discharge (ESD) protection to ±15kV IEC 61000-4-2 Airgap, ±15kV Human Body Model (HBM) and ±8kV IEC 61000-4-2 Contact. Full fail-safe protection is included on each receiver output to avoid system lockup, oscillation, or indeterminate states by defaulting to logic-high output level when the inputs are open, shorted, or terminated but undriven. XR3160E's high speed drivers operate up to 20Mbps in RS-485/422 modes, and up to 1Mbps in RS-232 mode. The RS-232 receiver inputs include a 5kΩ pull-down to ground when in RS-232 mode. The RS-485/422 receiver inputs are high impedance (>96kΩ), allowing up to 256 devices on a single communication bus (1/8th unit load). Operating from a single power supply from 3V to 5.5V, the shutdown mode consumes less than 1μA in low power standby operation with RS-232 receivers enabled. All drivers can be slew limited to 250kbps in any mode to minimize electromagnetic interference (EMI) by setting the dedicated SLEW pin low.

Exar offers an evaluation board for the XR3160E RS-232/RS-485/RS-422 Transceivers.
