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 TP75176E is available in an SOP-8 and MSOP-8
package, and is characterized from –40° to 125°
