3PEAK’s TPT4031 is an enhanced RS422 device whichmeets standard TIA/EIA-422-B with strong ESDprotection capability. The BUS-pin can pass ±18kV HBMESD, and ±15 kV IEC-Air ESD protection. It works inwide power supply range: from 3.0V to 5.5V VCC, whichprovides quad driver for balanced communication. It alsofeatures the larger output voltage and higher data rate,the TPT4031 can generate 3.9V differential output with100-Ω Load and 50Mbps data rate in 5.0V power supply,required by high speed field-bus applications. The devicecan generate 30mA high output drive current, with shortprotect function in some abnormal operations, the clampcurrent is less than 150mA.The TPT4031’s enable functions can control all fourdrivers and provide an active-high (G) or active-low (/G)enable input, and they provide the high-impedance statein the power-off condition, which only consume 6uA verylow current.The TPT4031 is available in an SOP16, and TSSOP16package, and is characterized from –40°C to 125°C.
