TPT481-VS1R

Drivers, Receivers, Transceivers Overview

The TPT481-VS1R is a half-duplex RS-485 transceiver manufactured by 3PEAK, designed for balanced communication networks. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 20 Mbps. The device presents a true 1/8 unit load to the bus, enabling the connection of up to 256 nodes without repeaters. It features full fail-safe receiver inputs that ensure a logic-high output during open, shorted, or terminated idle states. The component includes robust ESD protection with ±18-kV HBM and ±15-kV IEC61000-4-2 ratings on bus pins. It is housed in an MSOP8 package and is characterized for operation across a temperature range of –40°C to 125°C.

Drivers, Receivers, Transceivers Feature Summary

• Exceeds EIA-485 standard requirements with hot-plug circuitry keeping outputs in three-state during power-up and power-down
• Supports high-speed communication at 20 Mbps while maintaining low bus current for extensive network scalability
• Integrates full fail-safe receiver design to guarantee logic-high output under floating, shorted, or undriven bus conditions
• Provides comprehensive bus-pin protection against electrostatic discharge events including contact and air discharge

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix VS1R corresponds to the MSOP8 package configuration when sourcing components. Confirm the tape and reel quantity matches project requirements, as this variant typically ships in reels of 3000 units. Ensure the procurement documentation references the correct RoHS-compliant green status and MSL rating for assembly planning purposes.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT481-VS1R when a compact MSOP8 footprint is required for space-constrained designs. This model is appropriate for applications demanding 20 Mbps throughput and support for up to 256 nodes on a single bus segment. Consider this part for environments requiring extended industrial temperature ranges and high ESD immunity levels.

Drivers, Receivers, Transceivers Part Context
