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.

Standard Products

STMicroelectronics Standard Products are a broad range of industry-standard and drop-in replacements for the most popular general-purpose analog ICs, discretes, and serial EEPROMs. The Standard Products are manufactured to the highest quality standards with many AECQ-qualified for automotive applications. A comprehensive set of STMicroelectronics design aids, including SPICE, IBIS models, and simulation tools, is available to make adding to a design-in easy.

Low-Power High-Speed Transceivers

STMicroelectronics Low-Power, High-Speed Transceivers are designed for RS-485, RS-422, and RS-423 communication applications. They usually contain one driver and one receiver in a half-duplex configuration. Each driver output and receiver input is protected against electrostatic discharge up to ±15kV and has no latch-up. These STMicroelectronics Low-Power, High-Speed Transceivers operate with a 5V supply and draw a very low supply current when unloaded or fully loaded but with disabled drivers. A SERCOS interface controller for industrial control systems enables real-time communication via optical fiber rings, RS-485 rings, and RS-485 buses.
