ISO1430
Overview
The ISO14xx devices are galvanically-isolated differential line transceivers for TIA/EIA RS-485 and RS-422 applications. These noise-immune transceivers are designed to operate in harsh industrial environments.
- 1 Compatible with TIA/EIA-485-A
- PROFIBUS compatible at 5-V bus-side supply
- Bus I/O protection - ± 30 kV HBM - ±16 kV IEC 61000-4-2 Contact discharge - ± 4 kV IEC 61000-4-4 Electrical fast transient
- Low-EMI 500-kbps, 12 Mbps and 50 Mbps Data Rates
- 1.71-V to 5.5-V logic-side supply (VCC1), 3-V to 5.5-V bus-side supply (VCC2)
- Failsafe receiver for bus open, short, and idle
- 1/8 Unit load up to 256 nodes on bus
- 100-kV/µs (typical) high common-mode transient immunity
- Extended temperature range from -40°C to +125°C
- Glitch-free power-up and power-down for hot plugin
