Product Overview
The TCAN1042-Q1 is a Texas Instruments automotive CAN FD transceiver for high-speed CAN physical layer designs. It supports ISO 11898-2:2016 and ISO 11898-5:2007 and is AEC-Q100 Grade 1 qualified for automotive applications. Functional safety documentation is available to aid functional safety system design.
The device family supports Classic CAN and 2-Mbps CAN FD operation, with G-suffix variants supporting 5-Mbps flexible data rate. Base TCAN1042-Q1 devices provide ±58 V bus fault protection, while H variants provide ±70 V bus fault protection. Receiver common-mode input voltage is ±30 V, and typical loop delay is 110 ns.
Package options include SOIC (8) 4.90 mm x 3.91 mm and VSON (8) 3.00 mm x 3.00 mm. The 8-pin pinout assigns TXD, GND, VCC, RXD, NC/VIO, CANL, CANH, and STB to pins 1 through 8. V-suffix devices use pin 5 as VIO for input threshold and RXD output level shifting, while non-V devices use pin 5 as NC.

Procurement Notes
When requesting a quote for TCAN1042-Q1, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What type of device is the TCAN1042-Q1?
The TCAN1042-Q1 is a Texas Instruments automotive CAN FD transceiver in the Signal_Chain category. It supports Classic CAN, 2-Mbps CAN FD operation, and high-speed CAN physical layer standards ISO 11898-2:2016 and ISO 11898-5:2007.
What packages are listed for the TCAN1042-Q1?
The listed package options are SOIC (8) measuring 4.90 mm x 3.91 mm and VSON (8) measuring 3.00 mm x 3.00 mm. Both use the 8-pin pinout with TXD, GND, VCC, RXD, NC/VIO, CANL, CANH, and STB.
How do V-suffix TCAN1042-Q1 variants differ?
V-suffix devices provide a VIO pin on pin 5. The VIO supply is used for input threshold and RXD output level shifting, and RXD is driven to VIO instead of VCC on these variants.
What bus fault protection applies to TCAN1042-Q1 variants?
Non-H variants, including the base TCAN1042-Q1, provide ±58 V bus fault protection. H variants provide ±70 V bus fault protection, according to the device comparison facts.
