Overview

The TPT4181 is a 3.0 V to 5.5 V, IEC electrostatic discharge (ESD) protected RS-485 transceiver, and the device can support ±15 kV Contact Discharge on the transceiver bus pins without damage. The TPT4181 features a VIO logic supply pin allowing a flexible digital interface capable of operating as low as 1.65 V.

Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ω load. Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven bus. The TPT4181 is available in an DFN3X3-10L package, and is characterized from – 40°C to 125°C.
