MAX14782EAUA+

MAX14782EAUA+ is a 3.3V to 5V ESD-protected transceiver intended for half-duplex RS-485/RS-422 communication up to 500Kbps. This device is optimized for extended cable runs while maximizing tolerance to noise. Its integrated protection features include short-circuit-protected outputs, hot-swap functionality, and a true fail-safe receiver, guaranteeing a logic-high receiver output when inputs are shorted or open. Hotswap capability eliminates undesired transitions on the bus during power-up or hot insertion. The transceiver draws a 1.9mA (typ) supply current when unloaded or when fully loaded with the drivers disabled and draws less than 10µA (max) of supply current in low-power shutdown mode. It is used in applications such as motion controllers, field bus networks, encoder interfaces, and backplane buses.

• Integrated protection increases robustness, short-circuit-protected outputs
• True fail-safe receiver, hot-swap capability
• Supply voltage range from 3V to 5.5V, data rates up to 500Kbps
• Supply current is 1.9mA typical at (DE = VCC, RE = GND, no load)
• Shutdown supply current is 10µA maximum at (DE = GND, RE = VCC)
• Allows up to 32 transceivers on the bus
• Driver propagation delay is 20ns maximum at (RL = 54ohm, CL = 50pF)
• Receiver propagation delay is 200ns maximum at (CL = 15pF, VCC = +3V to +5.5V)
• Operating temperature range from -40°C to +125°C
• 8-pin µMAX package
