SN65HVD234DR Replacement Model
The SN65HVD234DR is a 3.3-V CAN (Controller Area Network) transceiver from Texas Instruments designed for use in automotive and industrial applications to facilitate communication between microcontrollers and devices within a network without a host computer.
For an alternative model, you can consider the SN65HVD235D which is also part of TI's family of CAN transceivers. Both chips share similar core functionalities but have different features tailored to specific needs.
SN65HVD234DR
Function: CAN Transceiver
Mode: Silent mode available (low-power mode)
Bus Fault Protection: Up to ±36 V
Data Rate: Up to 1 Mbps
Supply Voltage Range: 3.0 V to 3.6 V
This device provides differential transmit capability to the bus and differential receive capability for the CAN controller at signaling rates up to 1 Mbps. Designed for operation in especially harsh environments, it features cross-wire protection, loss-of-ground and overvoltage protection, overtemperature protection, as well as wide common-mode range.
Function: CAN Transceiver
Mode: Low-power mode with wake-up feature
Bus Fault Protection: Similar levels of fault protection
Data Rate: Up to 1 Mbps
Supply Voltage Range: Similar supply voltage range
The primary difference between this device and the SN65HVD234DR is that it includes a low-power standby function with wake-up signalization which allows nodes on a network that are not always needed online can be put into sleep mode until they are required.
Comparison:
While both devices serve as robust solutions for enabling reliable communication on a vehicle’s data bus or industrial networks there are some distinctions worth noting such as:
Operating Modes: The main difference lies in their power management capabilities; where the latter has an additional low-power standby state.
Features & Protections: They generally offer similar protective features against electrical faults ensuring reliability under adverse conditions.
