TPT480-DF6R

Drivers, Receivers, Transceivers Overview

The TPT480-DF6R is a full-duplex RS-485/RS-422 transceiver manufactured by 3PEAK. It operates on a single 3.0V to 5.5V supply and supports data rates up to 32Mbps. The device features robust bus-pin protection, including ±20kV HBM ESD, ±12kV IEC contact discharge, and ±15kV IEC air discharge. It incorporates hot-plug circuitry that keeps Tx and Rx outputs in a three-state condition during power-up or power-down events. The receiver utilizes a full fail-safe design to ensure a logic-high output when inputs are floating, shorted, or idle. The component is housed in an 8-lead DFN3x3 package with a thermal pad connected to ground.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DF6R corresponds to the DFN3X3-8L package configuration. Confirm the tape and reel quantity matches project requirements, as standard packaging is typically 4000 units per reel. Ensure the RoHS compliant status aligns with environmental regulations for the target deployment region.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring simultaneous bidirectional data transfer at speeds up to 32Mbps. The DFN3X3-8 package is suitable for space-constrained designs. Verify that the system voltage falls within the 3.0V to 5.5V range and that the load resistance meets the 54Ω requirement for optimal differential output voltage performance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT480/TPT482 family of full-duplex transceivers from 3PEAK. While the TPT482 includes enable pins (DE, /RE) for controlling driver and receiver states, the TPT480 variant lacks these controls, keeping both functions permanently active. This distinction defines the interface complexity required by the host microcontroller or processor.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the TPT480L1-SO1R, which offers identical electrical specifications but utilizes an SOP-8 package instead of the DFN3X3-8 form factor. Designers must account for footprint differences when swapping between these package options.

Drivers, Receivers, Transceivers FAQ

Does the TPT480-DF6R have enable pins for the driver and receiver?

No, the TPT480 variant does not include DE or /RE pins. Both the driver and receiver are fully enabled at all times, unlike the TPT482 which provides separate enable controls.

What is the input common-mode voltage range for this device?

The input common-mode range extends from -7V to +12V, allowing compatibility with various bus configurations and long cable runs.

How does the device handle hot-plugging scenarios?

The TPT480-DF6R features hot-plug circuitry that ensures the Tx and Rx outputs remain in a three-state condition during power-up or power-down, preventing erroneous data transmission onto the bus.
