Overview
The TPT487A is the enhanced RS485 which exceeds the standard TIA/EIA-485-A. The TPT487A is a single transceiver for balanced communication with a ±15-kV IEC-ESD protection and a 3-V to 5.5-V power. It also features the larger output voltage and higher data rate (up to 500 Kbps) required by high-speed PROFIBUS applications.
Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54-Ω load. These 500-Kbps 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.
This transceiver requires a 3-V to 5.5-V tolerance supply and delivers at least a 2.1-V differential output voltage on the 5-V supply condition. Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic-high Rx output if the Rx inputs are floating, shorted, or terminated but undriven. The Rx outputs feature high drive levels (typically > 25 mA @ VOL = 1 V) to ease the design of optically isolated interfaces. The TPT487A is available in the SOP8, MSOP8, and DFN3×3-8 packages, and is characterized from –40°C to 125°C.
