(PREVIEW) TIDA-00005
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
Description
This reference design provides an isolated, 40-Mbps, 3.3-V to 5-V Profibus interface using the ISO1176T, isolated Profibus transceiver and the TPS76350 high-accuracy linear regulator. This circuit achieves signal and power isolation and at the same time decreases board space and power consumption.
Features
- 4000V peak isolation, 560V peak VIORM
- Signaling rates up to 40Mbps
- Differential output exceeds 2.1V (54 Ohm load)
- Low bus capacitance of 10pF (Max)
- Fail-safe receiver for bus open, short, or idle
- This reference design is orderable
