TPT75176A数据手册3PEAK中文资料规格书

描述 Description

3PEAK’s TPT75176A/B is enhanced RS485 which exceeds standard TIA/EIA-485-A with ±12kV ESD 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°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 TPT75176A/B is available in an SOP8, MSOP8 and DFN3X3-8L package, and is characterized from –40°C to 125°C.
