Description

3PEAK’s TPT4032 is 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,

the TPT4032 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 TPT4032’s enable functions can control all four

receivers and provide an active-high (G) or active-low

(/G) enable input, and they provide the highimpedance state in the power-off condition, which

only consume <1uA very low current.

The TPT4032 is available in an SOP16 and

TSSOP16 package, and is characterized from –40°C

to 125°C.
