TJA1462AT/0Z - 8Mbit/s CAN FD SIC Transceiver | NXP
MPN: TJA1462AT/0Z ✓ AktifTJA1462AT/0Z Ringkasan
A CAN transceiver is the physical-layer interface between a digital bus controller and the differential CAN bus. The TJA1462 belongs to the TJA146x family of CAN and CAN FD transceivers, combining bus-driver, receiver, logic-level I/O, and standby functionality in one IC. The VIO pin permits the logic-side supply voltage to be selected independently from the transceiver supply, while STB provides a low-power control input.
The TJA1462 supports reliable CAN FD communication at data rates up to 8 Mbit/s. According to the manufacturer product information, reducing signal ringing and improving bit-timing symmetry enables larger CAN FD networks. CAN SIC also improves compatibility in installations where long stubs, unequal trace lengths, or multiple termination conditions would otherwise distort edge timing. Standby mode provides a practical way to reduce activity when the network is not being used.
The device is intended as a retrofit option for existing high-speed Classical CAN and CAN FD designs using compatible NXP transceivers such as the TJA1042 or TJA1044. NXP states that the TJA1462 offers pin compatibility and is designed to avoid hardware and software changes. The TJA1462AT variant uses the SO8 package, while the HVSON8 option is a different package and is therefore not a drop-in substitute.
Typical uses include automotive CAN FD gateways, electric-vehicle body controllers, industrial vehicle networks, engine controllers, lighting controllers, and battery-management systems. The 150°C temperature indication associated with the AT automotive ordering variant makes it suitable for applications requiring an extended automotive temperature range, subject to the complete datasheet limits and qualification requirements.
When laying out a TJA1462AT/0Z board, follow the manufacturer's recommended bus and ground connections, place transceiver decoupling close to the supply pins, and preserve the CAN bus routing and termination guidance in the datasheet. The IC reduces ringing but cannot compensate for an incorrect topology, excessive stub length, poor grounding, or unsuitable termination.
This page consolidates the verified NXP product information, manufacturer datasheet link, distributor pricing, pinout, and application guidance with a focus on practical CAN FD integration, retrofit decisions, and same-package replacement constraints.

Automotive CAN FD Gateway
The TJA1462AT/0Z fits an automotive CAN FD gateway because it supports communication at up to 8 Mbit/s and combines a CAN bus interface with CAN Signal Improvement Capability. According to the NXP documentation, reduced signal ringing and improved bit-timing symmetry can support larger networks where unequal routing or stub lengths might otherwise degrade edge timing. The gateway controller connects through TXD and RXD, while VIO accommodates a separate logic-side supply. Before schematic release, verify the complete transceiver electrical limits, transceiver supply requirements, standby polarity, and the manufacturer's recommended bus and termination layout.

Electric Vehicle Body Controller
The TJA1462AT/0Z is appropriate for an electric-vehicle body controller that exchanges diagnostics, status, and actuator commands over a CAN FD network. Its 8 Mbit/s capability supports high-rate communication, while CAN SIC addresses signal ringing and improves bit-timing symmetry on networks affected by long branches or complex wiring. The AT ordering variant is associated with an automotive SOIC-8 format and a 150 °C temperature indication in the verified distributor data. Designers should still confirm the complete electrical and qualification requirements for the exact MPN before using it in a safety-relevant or temperature-critical vehicle function.

Industrial Vehicle Network Controller
The TJA1462AT/0Z suits CAN FD nodes in construction, agricultural, and material-handling vehicles where a long wiring harness can produce reflections or uneven edge timing. Supporting data rates up to 8 Mbit/s preserves CAN FD throughput, while reduced ringing and improved bit-timing symmetry provide additional margin for network reliability. The device is placed between the host CAN controller and the CANH/CANL bus, with VIO supporting the controller's logic supply and STB providing standby control. The PCB must follow the NXP pin configuration and recommended termination scheme, including appropriate bus biasing where required.

Its 8 Mbit/s capability supports responsive communication without requiring a separate bus interface, and CAN SIC improves edge integrity on vehicle networks with substantial harness branches. The SOIC-8 format allows a compact implementation, while VIO decouples the host logic supply from the transceiver supply and STB supports controlled low-power states. Designers must validate the power rails, ground strategy, bus topology, and thermal performance against the complete NXP datasheet.

Catatan Desain
Use the NXP TJA1462 recommended application layout for the SO8 footprint and preserve the documented CANH and CANL routing. Keep the transceiver close to the bus connector and minimize stub length, because CAN SIC can improve edge behavior but cannot correct an unnecessarily long branch. Follow the datasheet's guidance on ground connections, bus termination, common-mode range, and decoupling rather than treating the reduced-ringing capability as a substitute for correct topology.
Provide separate, properly decoupled VCC and VIO supplies in accordance with the manufacturer datasheet. The VIO input allows the controller-side interface voltage to be selected independently, but each rail still requires correct sequencing, voltage-level compatibility, and local bypass capacitance. Place the decoupling capacitor adjacent to the relevant supply pin and use a low-impedance ground return so that current from CAN bus disturbances does not modulate the host controller's supply.
Do not substitute the HVSON8 TJA1462ATK or TJA1462BTK for the SO8 TJA1462AT/0Z without changing the PCB footprint and pin layout. Also verify the STB polarity and active level rather than assuming that every NXP CAN transceiver uses identical standby behavior. A package match alone is insufficient for a production drop-in decision; compare TXD, RXD, VIO, supply, sleep-current, wake-up, and fault-mode behavior against the complete manufacturer datasheets.
For networks with long harnesses, unequal routing, or multiple stubs, evaluate the TJA1462 in the completed topology rather than relying only on a bench link. CAN SIC reduces ringing and improves bit-timing symmetry, but margin still depends on termination placement, common-mode voltage, transceiver thresholds, and controller timing. Measure recessive and dominant edges at the worst-case bus endpoint and confirm that the selected CAN FD bit rate and sample point remain compliant.
For an automotive or industrial installation, calculate power dissipation from the actual VCC-to-ground operating current and the ambient temperature at the transceiver location. The verified distributor data identifies a 150 °C temperature indication for the AT variant, but that does not replace a full thermal design. Confirm the datasheet's maximum junction and ambient ratings, maintain copper around all eight SOIC pins where practical, and avoid placing the transceiver next to a heat source that reduces its available operating margin.
