TPT7481

Isolated Full- and Half-Duplex RS485 Transceiver

Overview

The TPT7481 is a ±15-kV IEC61000 ESD protected, 3.0-V ~ 5.5-V isolated RS485 transceivers that meet the RS-485 and RS-422 standards for Half Duplex communication. The TPT7482 is isolated Full Duplex RS485.

The TPT748x features a fail-safe receiver, which supports the output of the receiver to be logic high when the differential input (bus pin A/B) of the receiver is open, short, or idle.

Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54-Ω load. The 20-Mbps device has 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 TPT748x is available in the WSOP16 package and is characterized from -40°C to +125°C.
