TPT75176B-SO1R

Drivers, Receivers, Transceivers Overview

The TPT75176B-SO1R is a half-duplex RS-485 transceiver manufactured by 3PEAK, designed for balanced communication in industrial environments. 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. It includes full fail-safe receiver functionality, ensuring a logic high output when inputs are floating or shorted. Characterized for operation from -40°C to +125°C, it utilizes an SOP-8 package with a quiescent supply current as low as 0.1 mA in shutdown mode.

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 table. Confirm that the component meets RoHS compatibility and halogen-free requirements specified under the manufacturer's green product definition before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT75176B variant over the TPT75176A when higher ESD robustness is required, specifically ±12-kV IEC-ESD contact protection compared to the A variant's ±8-kV rating. Ensure the application requires half-duplex communication and can accommodate the 1/4 unit load specification for up to 128 nodes on the bus. Verify thermal management needs based on the SOP-8 package thermal resistance values provided in the datasheet.

Drivers, Receivers, Transceivers Part Context
