TPT487L1-DF6R

Drivers, Receivers, Transceivers Overview

The TPT487L1-DF6R is a half-duplex RS-485 transceiver manufactured by 3PEAK, housed in a DFN3X3-8 package. It operates on a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 Kbps. The device presents a true 1/8 unit load to the bus, enabling networks with up to 256 nodes without repeaters. It features full fail-safe receiver inputs that ensure a logic-high output during open, shorted, or idle terminated conditions. ESD protection ratings include ±18 kV HBM, ±15 kV IEC contact discharge, and ±18 kV IEC air discharge. The quiescent supply current is typically 750 µA when both driver and receiver are enabled.

Drivers, Receivers, Transceivers Feature Summary

• Hot plug circuitry maintains three-state outputs during power-up and power-down events
• Full fail-safe receiver design ensures high output state under fault conditions
• Robust bus-pin protection against electrostatic discharge and transient events
• Low bus current consumption allows for extensive multi-drop network topologies

Drivers, Receivers, Transceivers Applications

• Motor drives
• Industrial control systems
• Communication infrastructure

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DF6R corresponds to the DFN3X3-8 package and tape-and-reel quantity of 4000 units. Confirm the RoHS-compliant green status and MSL rating before finalizing procurement orders. Ensure the supplier provides traceability documentation matching the manufacturer's specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring compact surface-mount solutions with robust ESD immunity. The DFN3X3-8 package offers thermal advantages over SOP variants. Verify that the system's operating temperature falls within the -40°C to 125°C range and that the 500 Kbps rate meets the communication requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TPT487 series of 3-V to 5.5-V RS-485 transceivers from 3PEAK. The series includes SOP8 and MSOP8 variants alongside the DFN3X3-8 option. All members share identical electrical characteristics and functional behavior, differing only in physical package dimensions and thermal performance metrics.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include TPT487L1-SO1R (SOP8) and TPT487-VS1R (MSOP8). Cross-vendor substitution requires verification of pinout compatibility, ESD protection levels, and unit load specifications.
