Overview
Description
The RAA788158 5V half-duplex powered RS-485/RS-422 transceiver features high output drive and high EFT and ESD protection. The device is immune to ±5kV IEC 61000-4-4 EFT transients and can withstand up to ±16.5kV IEC 61000-4-2 ESD strikes without latch-up.
The RAA78815x family includes half and full-duplex transceivers with active-high driver-enable pins and active-low receiver-enable pins. These transceivers support data rates of 115kbps, 1Mbps, and 20Mbps with a performance that is characterized from -40 °C to +85 °C.
Features
- High VOD: 3.1V (Typ.) into RD = 54Ω
- ±5kV EFT immunity of bus I/O pins
- ±16.5kV ESD protection on bus I/O pins
- Supported data rates: 20Mbps
- Full fail-safe outputs for open or shorted inputs
- Hot plug capability
- 1/8 unit load
- Allows for up to 512 transceivers on the bus
- Low supply current (driver disabled): 550μA
- Ultra-low shutdown current: 70nA
