TPT481

3.0V to 5.5V RS-485 Transceivers

Overview

The TPT481 are IEC61000 ESD protected, 3.0V to 5.5V powered transceivers that meet the RS-485 and RS-422 standards for balanced communication.

Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ω load. These 20Mbps devices have very low bus currents so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without using repeaters. 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. 

TPT481 is designed for half-duplex RS485, and support SOP8, MSOP8 and DFN3X3-8L package, which is characterized from –40°C to 125°C
