TPT486-SO2R

Drivers, Receivers, Transceivers Overview

The TPT486-SO2R is a full-duplex RS-485/RS-422 transceiver manufactured by 3PEAK. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 500 Kbps. The device features hot-plug circuitry, ensuring transmitter and receiver outputs remain in a three-state condition during power-up or power-down sequences. It provides robust bus-pin protection against electrostatic discharge, including ±20 kV HBM, ±12 kV IEC contact, and ±15 kV IEC air discharge ratings. The input common-mode range spans from -7V to +12V, and the receiver incorporates a full fail-safe design that guarantees a logic high output when inputs are open, shorted, or terminated but undriven. The component is characterized for operation across an ambient temperature range of -40°C to 125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix SO2R corresponds to the 14-pin SOP package configuration required for the target PCB layout. Confirm the MSL rating and tape and reel quantity specifications align with assembly line capabilities. Ensure the green RoHS-compliant status meets environmental compliance requirements for the final product deployment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 connectivity with high noise immunity. The wide input common-mode range and integrated ESD protection make it suitable for harsh industrial environments. Verify that the 500 Kbps data rate satisfies the network throughput requirements and that the 14-pin package fits the available board space constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT486/488 family of 3.3V and 5.0V full-duplex RS-485 transceivers. The TPT486 variant specifically utilizes a 14-pin SOP package, distinguishing it from the TPT488 which offers 8-pin SOP and DFN options. All variants share identical electrical characteristics and functional behaviors, differing only in physical footprint and pin count.

Drivers, Receivers, Transceivers FAQ

What is the behavior of the receiver output when the bus inputs are left floating?

The full fail-safe design ensures a logic high receiver output when the Rx inputs are open, shorted, or on a terminated but undriven bus.

How does the device handle hot-plugging events?

Hot-plug circuitry keeps the Tx and Rx outputs in a three-state condition during power-up and power-down, preventing wrong data transmission.

What is the maximum supported data rate for this transceiver?

The device supports a maximum data rate of 500 Kbps.
