Protected, 3.0~5.5V 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° to +125°
C
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 TPT75176A/B is available in an SOP8, MSOP8 and
DFN3X3-8L package, and is characterized from –40° to
C
125°
C.
