Product Overview
The SN65HVD230 is a Texas Instruments 3.3-V CAN bus transceiver for Signal_Chain designs requiring ISO 11898-2 High Speed CAN physical-layer compatibility. It is designed for signaling rates up to 1 Mbps and supports up to 120 nodes on one bus through high input impedance.
The device operates from a 3.0 to 3.6 V VCC range and is specified for -40 to 85 °C operating free-air temperature. Bus operating limits include -2 to 7 V common-mode bus voltage, -2.5 to 7.5 V separate bus terminal voltage, and -6 to 6 V differential input voltage. Absolute maximum limits include -0.3 to 6 V supply voltage, -4 to 16 V CANH or CANL voltage, and -25 to 25 V CAN transient pulse voltage through 100 ohm.
The SOIC-8 package has a 4.90 mm x 3.91 mm nominal body size. Pin functions include an RS mode-control input for high-speed, low-power, or slope-control operation and a Vref output equal to VCC / 2. ESD ratings include ±16 kV HBM on CANH, CANL, and GND, ±4 kV HBM on all pins, and ±1 kV CDM.

Procurement Notes
When requesting a quote for SN65HVD230, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What supply voltage does the SN65HVD230 use?
The SN65HVD230 uses a recommended VCC supply range of 3.0 to 3.6 V. The absolute maximum supply voltage rating is -0.3 to 6 V over the operating free-air temperature range.
What CAN physical layer does SN65HVD230 support?
The device is specified for ISO 11898-2 High Speed CAN compatibility. Its designed signaling rate is up to 1 Mbps, and its high input impedance allows up to 120 nodes on one bus.
How is the RS pin used on SN65HVD230?
For SN65HVD230, pulling RS down to GND selects high-speed mode, pulling it up to VCC selects low-power mode, and using a 10 kOhm to 100 kOhm pulldown enables slope-control operation.
What ESD ratings are specified for this transceiver?
The CANH, CANL, and GND pins are rated for ±16 kV HBM under ANSI/ESDA/JEDEC JS-001. All pins are rated for ±4 kV HBM, and the charged-device model rating is ±1 kV.
