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.
