TJA1042T in NXP TJA CAN Transceivers Family
The TJA1042T series is a family of high-speed CAN transceivers manufactured by NXP Semiconductors, designed to interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. These devices act as a bridge, providing differential transmit and receive capability. They are specifically optimized for automotive and industrial applications, offering excellent Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) performance, while ensuring reliable communication at data rates up to 5 Mbit/s in CAN FD environments.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| TJA1042T/3/CM,118 (NXP Semiconductors) | /CM,118 | 8,097 |
| TJA1042T/3/1J (NXP Semiconductors) | /1J | 2,517 |
| TJA1042T/CM,118 (NXP Semiconductors) | CM,118 | 1,878 |
Variants within the TJA1042T sub-family are distinguished primarily by their supply voltage compatibility and pin configurations. For instance, the '/3' suffix indicates an integrated 3.3V voltage regulator input (VIO) for seamless interfacing with low-voltage microcontrollers. Some versions focus on enhanced Standby mode capabilities for power-sensitive applications, while different suffixes like 'CM' relate to specific lead-free packaging standards or assembly site logistics, though core electrical parameters remain consistent across the sub-family.
