Product details

CAN physical-layer transceiver for 5V industrial buses

The part integrates one driver and one receiver, with 200 mV of receiver hysteresis to reject bus noise and ensure clean signal recovery on long or noisy cable runs.

5 V supply — 3.3 V logic interface note

The logic input pins (TXD) and output (RXD) swing with the VCC rail, so direct connection to a 3.3 V controller's UART pins exceeds the logic-low threshold but leaves the logic-high margin thin. A level shifter or a resistor divider on TXD and a clamp on RXD is recommended when pairing with a 3.3 V MCU.

Frequently asked questions

Is SN65HVD256D compatible with 3.3V logic?

Not directly. For a 3.3V controller, use a level translator or a resistive divider on TXD and a clamping diode on RXD to avoid overstressing the MCU pins.

What is the difference between SN65HVD256D and SN65HVD256DR?

The SN65HVD256D ships in a Tube, while the SN65HVD256DR ships in Tape & Reel. The die, package, and electrical specifications are identical. Order the D variant for prototype or low-volume builds and the DR variant for automated pick-and-place assembly.

Is SN65HVD256D obsolete or nearing end of life?

No. The SN65HVD256D is listed as Active by Texas Instruments.
