3V Full-Duplex, 0.25 Mbps RS-485/422 Differential Transceiver with ±3kV EFT Immunity and ±10kV ESD Protection
Jump to Page Section:
Overview
Description
The RAA788170 3V full-duplex powered RS-485/422 transceiver features a high output drive and high EFT and ESD protection. The device is immune to ±3kV IEC 61000-4-4 EFT transients and can withstand up to ±10kV IEC 61000-4-2 ESD strikes without latch-up.
The RAA78817x 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 250kbps, 500kbps, and 20Mbps with a performance that is characterized from -40 °C to +85 °C.
Features
- IEC61000 ESD protection on RS-485 I/O pins: ±16.5kV
- Class 3 ESD level on all other pins: >7kV HBM
- ±3kV EFT immunity of bus I/O pins
- Full fail-safe (open, short, terminated/floating) receivers
- Hot plug - Tx and Rx outputs remain three-state during power-up
- True 1/8 unit load allows up to 256 devices on the bus
- Single 3.3V supply
- High data rates: up to 250 Kbps
- Low quiescent supply current: 800μA (Max)
- Ultra-low shutdown supply current: 10nA
- -7V to +12V common-mode input/output voltage range
- Half and full duplex pinouts
- Current limiting and thermal shutdown for driver overload protection
- Tiny MSOP packages consume 50% less board space
- Pb-free (RoHS compliant)
