TCAN332DR

Drivers, Receivers, Transceivers Overview

The TCAN332DR is a high-speed CAN FD transceiver from the Texas Instruments TCAN33x family, designed for 3.3V single-supply operation. It supports data rates up to 1 Mbps and complies with ISO 11898-2 standards. The device features a wide common mode range of ±12V and bus pin fault protection of ±14V. It includes integrated ESD protection exceeding ±25kV HBM and ±12kV IEC contact discharge. Electrical characteristics specify a supply voltage range of 3V to 3.6V, an operating temperature range of -40°C to 125°C, and a total loop delay of less than 135ns. It utilizes an 8-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dominant time out (DTO) functions for driver and receiver to enhance network robustness against local faults.
• High electromagnetic compatibility performance achieved through matched dominant and recessive common modes.
• Glitch-free power-up and power-down behavior ensures safe operation during voltage transitions.
• Bus and logic pins maintain high impedance when unpowered, preventing loading on the active bus.

Drivers, Receivers, Transceivers Applications

• Industrial automation, control systems, sensors, and drive systems
• Building, security, and climate control automation
• Telecom base station status and control networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-8 package variant. Confirm that the component meets RoHS compliance requirements for the target assembly process. Ensure the supply chain source provides valid traceability documentation consistent with Texas Instruments production standards.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring standard 1 Mbps CAN communication without low-power standby or shutdown modes. The TCAN332 lacks the additional control pins found in TCAN330 or TCAN334 variants. Verify that the system design accommodates the normal mode operation only constraint defined by the NC pins.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TCAN33x series of 3.3V CAN transceivers. Unlike the TCAN332G which supports 5 Mbps, the non-G suffix indicates a 1 Mbps specification. It serves as a drop-in replacement for legacy 3.3V CAN interfaces while offering improved EMC and protection features compared to older generations.

Drivers, Receivers, Transceivers FAQ

Does the TCAN332DR support low-power standby or shutdown modes?

No, the TCAN332DR operates only in normal mode. Pins 5 and 8 are No Connect (NC), so it does not support the standby or shutdown functionalities available in TCAN334 or TCAN330 variants.

What is the maximum data rate supported by the TCAN332DR?

The TCAN332DR is specified for data rates up to 1 Mbps. The 5 Mbps capability is reserved for the TCAN33xG devices.

How does the device handle bus faults?

It provides bus pin fault protection of ±14V and includes Driver Dominant Time Out (TXD DTO) and Receiver Dominant Time Out (RXD DTO) to release the bus in case of stuck dominant conditions.
