TP8485E
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the TP8485E family does
The TP8485E is a full fail-safe RS-485 transceiver offering ±18kV ESD protection and a data rate from 300 bps to 250 kbps. This device operates on a 3V to 5.5V supply, supports up to 256 nodes on a bus, and features a 1/8 unit load. Available in SOIC-8 and MSOP-8 packages, it functions across a temperature range of -40°C to +125°C. Engineers typically use this component in industrial automation, HVAC systems, process control, and battery-powered applications where robust differential communication is required.
