TCAN1042DRQ1

TCAN1042DRQ1 is a Texas Instruments AEC-Q100 Grade 1 CAN FD transceiver in SOIC-8, compliant with ISO 11898-2:2016 and ISO 11898-5:2007, for automotive and industrial CAN nodes that need classic CAN plus CAN FD at up to 2 Mbps from a 4.5 V to 5.5 V supply. The parameter that carries the design is bus robustness: plus/minus 58 V bus-fault protection, a plus/minus 30 V receiver common-mode range, IEC ESD of plus/minus 15 kV and a typical 110 ns loop delay keep communication alive on noisy harnesses with ground shifts and load transients. Standby mode with remote wake support and a TXD dominant time-out that works down to 10 kbps protect the node against a stuck controller pin while keeping parked-vehicle current low. Selection advice: order the DRQ1 tape-and-reel code — the tube-packaged TCAN1042DQ1 is obsolete, so do not mix the two on a BOM. If the network needs 5 Mbps CAN FD, step to the G option of this family; for plus/minus 70 V bus tolerance choose the H variant, and for logic level shifting to a low-voltage MCU choose the V variant with VIO. Parameters verified against the TI TCAN1042-Q1 datasheet (Rev. D package addendum lists this code as Active, in production).
