ST3485EI Datasheet | STMicroelectronics

Features - ESD protection - ±15 k V IEC 61000-4-2 air discharge - ±8 k V IEC 61000-4-2 contact discharge - Operate from a single 3.3 V supply - no charge pump required - Interoperable with 5 V logic - 1 µA low current shutdown mode max. - Guaranteed 12 Mbps data rate - -7 to 12 V mon mode input voltage range - Half duplex versions available - Industry standard 75176 pinout - Current limiting and thermal shutdown for driver overload protection - Guaranteed high receiver output state for floating inputs with no signal present - Allow up to 64 transceivers on the bus - Available in SO8 package - Automotive grade (ST3485EIY) Description The ST3485EB, ST3485EC, ST3485EI and ST3485EIY devices are ±15 k V ESD protected, 3.3 V low power transceiver for RS-485 and RS-422 munications. These devices contain one driver and one receiver in half duplex configuration. These devices transmit and receive at a guaranteed data rate of at least 12 Mbps. All transmitter outputs and receiver inputs are protected to ±15 k V IEC 61000-4-2 air discharge. The driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state.
