Product details

8 Mbps CAN FD transceiver for automotive networks

The device integrates a single driver and receiver, with receiver hysteresis of 140 mV for noise immunity on the bus. Supply voltage spans 4.5V to 5.5V on the VIO pin and 4.5V to 40V on the VBAT pin, allowing direct connection to a 12V or 24V battery system or a regulated 5V rail.

Housed in a 14-pin SOT-23 Thin variant (SOT-23-14), the TCAN1043ADYYRQ1 is a surface-mount device with a compact footprint suited for space-constrained ECU layouts. The supplier device package is 14-SOT-23-THIN. The thin profile helps with low-profile board stacking.

This is a production-grade part for new designs, not a phase-out or NRND device.

Frequently asked questions

Does TCAN1043ADYYRQ1 support CAN FD?

Yes, with a data rate of 8 Mbps, the TCAN1043ADYYRQ1 supports CAN FD (Flexible Data Rate) communication, enabling higher throughput for modern automotive networks.

Is TCAN1043ADYYRQ1 pin-compatible with TJA1043?

The TCAN1043ADYYRQ1 is a functional equivalent in the CAN transceiver space, but pin compatibility with the NXP TJA1043 should be verified against the respective datasheets. The TCAN1043A family from TI is designed as a drop-in replacement for the TJA1043 in many applications, but always confirm the pinout for your specific layout.
