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 @ V
OL
= 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.
