描述 Description

3PEAK’s TPT75176H is enhanced RS485 which exceeds

standard TIA/EIA-485-A with ±15kV IEC-ESD Protected,

3V~5.5V powered, single transceiver for balanced

communication. It also features the larger output voltage

and higher data rate - up to 10Mbps - required by high

speed PROFIBUS applications, and is offered in Industrial

and Extended Industrial (-40°C to +125°C) temperature

ranges.

This transceiver requires a 3V~5.5V tolerance supply, and

delivers at least a 2.1V differential output voltage on 5V

supply condition. This translates into better noise immunity

(data integrity), longer reach, or the ability to drive up to

three 120Ω terminations in “star” or other non-standard

bus topologies, at the exceptional 10Mbps data rate.

Receiver (Rx) inputs feature a “Full Fail-Safe” design,

which ensures a logic high Rx output if Rx inputs are

floating, shorted, or terminated but undriven. Rx outputs

feature high drive levels (typically >25mA @ VOL = 1V) to

ease the design of optically isolated interfaces.

The TPT75176H is available in an SOP8, MSOP8 and

DFN3X3-8L package, and is characterized from –40°C to

125°C.
