AMIS42665TJAA3L

Drivers, Receivers, Transceivers Overview

The AMIS42665TJAA3L is a high-speed, low-power CAN transceiver manufactured by onsemi. It serves as the interface between a CAN protocol controller and the physical bus in 12 V and 24 V systems. The device supports data rates up to 1 Mbps with a supply voltage range of 4.75 V to 5.25 V. It features an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 package (Case 751). Key electrical parameters include a propagation delay of 90–245 ns, standby current typically 10 µA, and thermal shutdown at approximately 160°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides wake-up capability over the bus while in standby mode
• Includes VSPLIT pin for stabilizing recessive bus level to reduce electromagnetic emissions
• Features TxD dominant time-out function to prevent permanent bus blocking
• Offers thermal protection and short-circuit proof bus pins

Drivers, Receivers, Transceivers Applications

• Automotive networks requiring ISO 11898 compliance
• Industrial control systems operating in 12 V or 24 V environments
• Applications demanding extremely low current standby modes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' indicates NiPdAu plating for the SOIC-8 package, distinct from the standard Matte Sn versions. Confirm the tube shipping quantity is 96 units per tray. Ensure the version corresponds to unconditioned bus wake-up behavior where RxD signals immediately upon entering standby if a dominant state persists.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for robust electromagnetic compatibility in automotive or industrial settings. The NiPdAu finish is suitable for specific soldering requirements. Consider the unconditioned wake-up behavior if immediate RxD signaling during standby entry under fault conditions is acceptable for the system architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the AMIS-42665 family of high-speed CAN transceivers. It shares core functionality with variants like AMIS42665TJAA1G but differs in packaging finish and wake-up logic. The 'L' suffix specifically denotes the NiPdAu lead frame finish compared to the standard tin finishes found in other revisions.

Drivers, Receivers, Transceivers Replacement Considerations

AMIS42665TJAA1G is a functional substitute with identical electrical characteristics but uses a Matte Sn finish instead of NiPdAu. AMIS42665TJAA6G offers different wake-up behavior where the signal is inactive during permanent bus faults.
