Overview
Description
The RAA788152 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.

What is the Standard that tests for EFT Immunity?
The standard that defines the test for assessing a systems’ immunity to fast electrical transients is IEC61000-4-4. This standard defines test voltage waveform, range of test levels, test equipment, test set-up, and test procedure. Its object is to establish a common and reproducible reference for evaluating the ...

What is EFT?
EFT are electrical fast transients in the form of bursts that originate from switching transients due to the interruption (switching) of inductive loads, relay contact bounce, etc. When de-energized, inductive loads such as relays, switch contactors, or heavy-duty motors produce bursts of narrow high-frequency transients on the ...
