ST4E12x High-Speed 3.3V/5V RS485 Transceivers

STMicroelectronics ST4E12x High-Speed 3.3V/5V RS485 Transceivers are low-power differential line transceivers for data transmission in standard RS485 applications in half-duplex mode. ST4E1216 and ST4E1240 are compatible with 3.3V or 5V rail power supplies and operate from 3V to 5.5V. These transceivers operate at data rates up to 16Mbps (ST4E1216) and 40Mbps (ST4E1240). The components are ideal for multipoint applications over extended cable runs and are robust to ESD transients. In particular, the bus pins support ±12kV IEC 61000-4-2 contact discharge. The STMicroelectronics ST4E12x High-Speed RS485 Transceivers also feature robust hot-swap capability during on/off switching or hot insertion. The transceivers are available in the standard SO-8 package and operate with a -40°C to +125°C (ST4E1216) and -40°C to +85°C (ST4E1240) temperature range.
