TPT4032-SO3R

An enhanced RS422 device which meets standard TIA/EIA-422-B with strong ESD protection capability. The BUS-pin can pass ±18KV HBM-ESD, and ±15 kV IEC-Air Charge ESD protection. It works in wide power supply range: from 3.0V to 5.5V VCC, which design quad receiver for balanced communication. It also features the wide input common-mode voltage and higher data rate, can accept -7V~+12V common-mode differential input with 100 Ω Load and 50Mbps data rate in 5.0V power supply, required by high speed field-bus applications. The enable functions can control all four receivers and provide an active-high (EN) or active-low (/G) enable input, and they provide the high-impedance state in the power-off condition, which only consume <1uA very low current. Available in an SOP16 and TSSOP16 package, and is characterized from -40°C to 125°C.
