Overview
The TPT481 is a series of IEC61000 ESD protected, 3.0-V to 5.5-V 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 54-Ω load. These 20-Mbps 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. The TPT481 is designed for half-duplex RS485, and supports SOP8, MSOP8, and DFN3X3-8 packages, which are characterized from –40°C to 125°C.
