Overview
The TPT7487 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 TPT7488 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 500-kbps 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.
