Overview

3PEAK’s TPT4031 is an enhanced RS422 device which meets standard TIA/EIA-422-B with strong ESD protection capability. The BUS-pin can pass ±18kV HBMESD, and ±15 kV IEC-Air ESD protection. It works in wide power supply range: from 3.0V to 5.5V VCC, which provides quad driver for balanced communication. It also features the larger output voltage and higher data rate, the TPT4031 can generate 3.9V differential output with 100-Ω Load and 50Mbps data rate in 5.0V power supply, required by high speed field-bus applications. The device can generate 30mA high output drive current, with short protect function in some abnormal operations, the clamp current is less than 150mA.

The TPT4031’s enable functions can control all four drivers and provide an active-high (G) or active-low (/G) enable input, and they provide the high-impedance state in the power-off condition, which only consume 6uA very low current.

The TPT4031 is available in an SOP16, and TSSOP16 package, and is characterized from –40°C to 125°C.
