TPT480 TPT482

3.3V & 5.0V Full Duplex RS-485 Transceivers

Features

Description

⚫

Exceeds Requirements of Full Duplex EIA-485

The TPT480 and TPT482 is IEC61000 ESD protected,

which support ±12 kV IEC contact and ±15 kV IEC air

discharge. 3.0V ~ 5.5V transceivers that meet the RS-485

and RS-422 standards for Full Duplex communication.

Standard

⚫

Hot Plug Circuitry - Tx and Rx Outputs Remain Three-

State During Power-up/Power-down

Transmitters in this family deliver exceptional differential

output voltages into the RS-485 required 54Ω load. The

devices have very low bus currents so they present a true

“1/8 unit load” to the RS-485 bus. This allows up to 256

transceivers on the network without using repeaters.

⚫

Supply voltage: 3.0V ~ 5.5V

Input Common-mode Range: -7V ~ +12 V

Data Rate: 32Mbps

Up to 256 Nodes on a Bus (1/8 unit load)

Full Fail-safe Receiver (Open, Short, Terminated)

Bus-Pin Protection:

Receiver (Rx) inputs feature a “Full Fail-Safe” design,

which ensures a logic high Rx output if Rx inputs are

floating, shorted, or on a terminated but undriven bus.

±20 kV HBM ESD

±12 kV IEC61000-4-2 Contact Discharge

±15 kV IEC61000-4-2 Air Discharge

–40°C to 125°C Operation Temperature Range

The TPT480x is designed for full-duplex RS485, and

support SOP8, DFN3X3-8, MSOP10 and SOP14 package,

which is characterized from –40°C to 125°C.
