TCAN1057ADDFRQ1

TCAN1057ADDFRQ1 is the small-package code of TI's TCAN1057A-Q1 automotive CAN FD transceiver, electrically identical to the SOIC-8 code already listed in this catalog but delivered in an eight-pin thin SOT-23 (DDF) package. The device is AEC-Q100 Grade 1 qualified, supports CAN FD up to 5 Mbps (and 8 Mbps in simpler networks), runs from a 4.5 V to 5.5 V supply, tolerates ±58 V bus faults and carries a TXD dominant time-out that releases the bus down to 9.2 kbps equivalent traffic. It offers Normal and Silent modes — silent mode listens without transmitting, which suits diagnostic, logging and bus-monitoring nodes that must never disturb traffic — plus thermal shutdown protection, over a junction range of -40 °C to +150 °C. The DDF package marking is 2HEF and the code ships in 3,000-piece reels. Selection advice: pick this DDF code only when board area genuinely forces it, such as dense zonal controllers and sensor pods; the SOIC sibling is easier to probe, rework and second-source. Because the two codes share one datasheet, confirm the package suffix on the purchase order, not just the TCAN1057A base name. Parameters verified against Texas Instruments documentation.
