SN65HVD234DR

What is the SN65HVD234DR and What Are Its Key Verified Specifications?

The SN65HVD234DR is a 3.3-V CAN (Controller Area Network) transceiver from Texas Instruments, designed for robust communication in automotive and industrial applications. It operates from a 3.0-V to 3.6-V supply and supports signaling rates up to 1 Mbps, compliant with ISO 11898. The device is available in an 8-pin SOIC (D) package and features a sleep mode for low-power operation, making it ideal for battery-powered and energy-conscious systems. As of 2026-08-25, the SN65HVD234DR is in stock at XAIPART with 99,999 units available, priced at $0.9068 per unit for quantities of 1000 or more.

Key verified specifications include a bus fault voltage range of -36 V to 36 V, ESD protection of 16 kV (HBM), a common-mode input range of -12 V to 12 V, and support for up to 120 nodes on a single bus. The sleep mode current is typically 0.05 µA, while the silent mode (standby) draws 370 µA. The device operates over a temperature range of -40°C to 125°C and is RoHS compliant. Its LVTTL I/Os are 5-V tolerant, simplifying interfacing with 5-V microcontrollers.

How to Select and Design In the SN65HVD234DR: A Technical Guide

When selecting the SN65HVD234DR for your design, consider the following verified specifications:

  • Supply voltage: 3.0 V to 3.6 V (nominal 3.3 V)
  • Signaling rate: up to 1 Mbps
  • Bus fault voltage: -36 V to 36 V
  • ESD protection: 16 kV HBM
  • Common-mode input range: -12 V to 12 V
  • Number of nodes: up to 120
  • Sleep mode current: 0.05 µA (typical)
  • Silent mode current: 370 µA (typical)
  • Operating temperature: -40°C to 125°C
  • Package: SOIC-8 (D)

Design-in steps:

  1. Power supply: Connect VCC (pin 3) to a 3.3-V rail, and GND (pin 2) to ground. Decouple with a 100-nF capacitor close to the VCC pin.
  2. CAN bus interface: Connect CANH (pin 7) and CANL (pin 6) to the differential bus lines. Place a 120-Ω termination resistor at both ends of the bus to minimize reflections.
  3. Controller interface: Connect TXD (pin 1) to the CAN controller's transmit output and RXD (pin 4) to the controller's receive input. The LVTTL I/Os are 5-V tolerant, so direct connection to 5-V controllers is possible.
  4. Mode selection: Use the RS pin (pin 5) to select between normal, silent (standby), and sleep modes. For sleep mode, drive RS high; for normal operation, drive RS low. The device wakes on bus activity or a low-level on RS.
  5. Reference voltage: VREF (pin 8) provides a reference voltage output, typically used for biasing or as a reference for the controller's A/D converter. If unused, leave it floating.

For optimal EMC performance, keep the traces from the transceiver to the bus connector short and use a solid ground plane. The slew-rate control on the output stage helps minimize EMI.

What Are the Drop-In Alternatives and How Do They Compare?
