TPT4031-SO3R

Drivers, Receivers, Transceivers Overview

The TPT4031-SO3R is a high-speed quad differential RS-422 driver manufactured by 3PEAK. It meets TIA/EIA-422-B requirements and supports data rates up to 50Mbps with typical propagation delays of 8ns. The device operates on a single supply voltage ranging from 3.0V to 5.5V, delivering a typical differential output voltage of 3.9V into a 100Ω load at 5.0V. Key electrical parameters include ±30mA output drive current, 30µA typical quiescent supply current, and low pulse skew of 0.5ns. It features robust ESD protection (±18kV HBM) and short-circuit protection limiting clamp current to less than 150mA. The component is characterized for operation between -40°C and 125°C and is housed in a 16-pin SOP package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix SO3R corresponds to the 16-pin SOP package with tape and reel packaging containing 2500 units. Confirm the marking code T4031 matches the physical device. Ensure the selected variant aligns with the required operating temperature range of -40°C to 125°C. Cross-reference the RoHS compliance status as defined by the manufacturer's green product criteria.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring quad differential drivers compliant with RS-422 standards. It is suitable for environments demanding high ESD immunity and wide supply voltage flexibility between 3.0V and 5.5V. Consider the 16-pin SOP package constraints regarding thermal dissipation and PCB layout space. Evaluate the need for dual enable pins if complex bus arbitration or power management logic is required.

Drivers, Receivers, Transceivers Part Context

The TPT4031 series consists of quad differential drivers intended for high-speed serial communication. The TPT4031-SO3R specifically denotes the version packaged in a 16-pin Small Outline Package (SOP). This family complements other 3PEAK interface products like the TPT4032 receiver, forming complete RS-422 link solutions for industrial automation and sensor networks.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include the TPT4031-TS3R, which offers identical electrical performance but utilizes a 16-pin TSSOP package instead of SOP. Verify pinout compatibility and thermal characteristics when switching between these package variants.

Drivers, Receivers, Transceivers FAQ
