MAX14770EATA+T

Drivers, Receivers, Transceivers Overview

The MAX14770EATA+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +4.5V to +5.5V and supports data rates up to 20Mbps. The device features ±35kV HBM ESD protection on the A and B pins, along with true fail-safe receiver circuitry that ensures a logic-high output when inputs are open or shorted. It includes hot-swap capability, thermal shutdown at +160°C, and driver short-circuit protection. The component is housed in an 8-pin TDFN package with an exposed pad and is specified for an automotive temperature range of -40°C to +125°C.
