TPT75176A-SO1R

Drivers, Receivers, Transceivers Overview

The TPT75176A-SO1R is a half-duplex RS-485 transceiver manufactured by 3PEAK. It supports data rates up to 10 Mbps at a 5-V supply and operates within a wide voltage range of 3 V to 5.5 V. The device features ±12-kV IEC-ESD contact protection and ±15-kV air-discharge protection on bus pins, alongside ±12-kV HBM ESD protection. It provides full fail-safe receiver functionality for open, shorted, or terminated buses and supports up to 128 nodes on a bus due to its 1/4 unit load characteristic. Typical propagation delays are 35 ns with a typical skew of 10 ns. The component is characterized for industrial and extended industrial temperature ranges from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• High-speed communication capability supporting up to 10 Mbps data rates for demanding applications like PROFIBUS.
• Robust electrostatic discharge protection on bus pins meeting strict industrial standards for contact and air discharge.
• Full fail-safe receiver design ensures a logic high output state when inputs are floating, shorted, or undriven.
• Low quiescent supply current consumption enhances energy efficiency in battery-powered or always-on systems.

Drivers, Receivers, Transceivers Applications

• PROFIBUS DP and FMS Networks
• SCSI Fast 40 Drivers and Receivers
• Motor Controller and Position Encoder Systems
• Factory Automation and Field Bus Networks
• Industrial and Process Control Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix SO1R corresponds to the SOP-8 package and tape-and-reel quantity of 4,000 units as listed in the official order information. Confirm that the A variant matches the required ±12-kV IEC-ESD contact specification, distinguishing it from the B variant which offers higher contact protection levels. Ensure compatibility with the intended operating temperature range of -40°C to +125°C before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT75176A-SO1R when a half-duplex RS-485 interface requires 10 Mbps performance with moderate ESD robustness. This part is suitable for networks requiring up to 128 nodes on a single bus segment. Consider the TPT75176B if higher IEC-ESD contact protection (±12 kV vs ±8 kV) is needed, or choose alternative packages like MSOP8 or DFN3X3-8 if board space constraints dictate a smaller footprint than the standard SOP-8.

Drivers, Receivers, Transceivers Part Context

The TPT75176A belongs to the TPT75176 product family produced by 3PEAK, designed to exceed standard TIA/EIA-485-A requirements. It serves as an enhanced RS-485 transceiver offering improved noise immunity through larger differential output voltages. The family includes variants such as the TPT75176B with different ESD ratings and multiple package options including SOP8, MSOP8, and DFN3X3-8 to accommodate various PCB layout needs.
