The 14-VDFN package with wettable flank allows AOI inspection after reflow, a requirement for zero-defect automotive production lines. ## 135 mV hysteresis and single-channel topology The receiver hysteresis of 135 mV provides noise margin on the differential CAN bus, reducing false bit detection in electrically noisy environments like motor drives or alternator proximity. The single driver/receiver pair (1/1) is the standard node topology for a CAN FD endpoint; no redundant bus interface is present. With a supply range from 4.5V to 28V, this transceiver handles load-dump transients common in automotive 12V and 24V systems without external clamping. No last-time-buy or obsolescence risk is indicated for this order code.","metaTitle":"TCAN1144DMTRQ1 CAN Transceiver, 5 Mbps, AEC-Q100, 4.5V–28V","metaDescription":"TI TCAN1144DMTRQ1 automotive-grade CAN transceiver. 5 Mbps data rate, 4.5V–28V supply, 150°C TJ, AEC-Q100.
