Product details

The TCAN1044VDDFR is a Texas Instruments CAN FD transceiver that runs from a 1.7V to 5.5V supply, which means it interfaces directly with 1.8V microcontrollers without a level shifter. That saves two resistors and a FET on the BOM for low-voltage CAN nodes. Full-duplex operation and an 8 Mbps data rate support CAN FD frames at the higher bitrate phase.

The SOT-23-8 (TSOT-23-8) package is small enough for space-constrained PCBs but still hand-reworkable with hot air — just watch the orientation mark; the TSOT-23-8 has a subtle pin-1 bevel that can be hard to spot under a microscope.

Receiver hysteresis and bus noise margin

100 mV of receiver hysteresis helps reject noise on the CAN bus differential pair. In a noisy environment (motor drive, high-side switching), that hysteresis buys you a cleaner dominant/recessive decision without external filtering.

Frequently asked questions

Is TCAN1044VDDFR compatible with 1.8V microcontrollers?

Yes. With a supply voltage range of 1.7V to 5.5V, the TCAN1044VDDFR operates directly from a 1.8V rail, matching the I/O levels of common low-voltage MCUs without extra translation.

What is the difference between TCAN1044VDDFR and TCAN1044V?

The TCAN1044VDDFR is the tape-and-reel variant of the base TCAN1044V transceiver. The electrical specifications — 8 Mbps data rate, 1.7V–5.5V supply, 100 mV hysteresis — are identical. The 'DDFR' suffix denotes the SOT-23-8 package on tape-and-reel; the TCAN1044V may be offered in other package or reel options.
