TP8481-SO1R

Drivers, Receivers, Transceivers Overview

The TP8481-SO1R is a half-duplex RS-485 transceiver manufactured by 3PEAK, designed for balanced communication networks. It operates on a supply voltage range of 3.0V to 5.5V and supports data rates up to 20 Mbps. The device features a true 1/8 unit load configuration, enabling the connection of up to 256 nodes on a single bus without repeaters. It includes full fail-safe receiver inputs that ensure a logic-high output when inputs are floating, shorted, or undriven. The component provides robust protection against electrostatic discharge (ESD) with ratings of ±18 kV HBM and ±15 kV IEC contact discharge. It is housed in an SOP-8 package and functions within an ambient temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed data transmission at rates up to 20 Mbps while maintaining low bus current consumption.
• Features full fail-safe receiver design to guarantee a logic-high output during open-circuit, short-circuit, or undriven bus conditions.
• Incorporates hot-plug circuitry that keeps transmitter and receiver outputs in a three-state condition during power-up and power-down events.

• Motor drive systems
• Industrial control equipment
• Communication infrastructure

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SO1R' against official 3PEAK documentation to confirm it denotes the SOP-8 surface-mount package and tape-and-reel quantity. Ensure the part number matches the exact electrical specifications required for your RS-485 network design, particularly regarding the 20 Mbps data rate and ESD protection levels.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed RS-485 communication with extensive node counts. The 1/8 unit load capability allows for large network topologies. Verify that the system environment requires the specified wide operating temperature range and that the 3.0V to 5.5V supply voltage aligns with the target platform's power architecture.
