Product details

LIN bus physical layer in a small exposed-pad package

The receiver includes 175 mV of hysteresis for noise rejection on the bus, which matters when routing the LIN line through the engine bay or near ignition-noise sources. The junction temperature rating of -40°C to 150°C means this transceiver is specified for under-hood and other high-temperature automotive environments where standard commercial-grade parts would fail.

Supply rail and temperature — the fit decisions

The 5V to 18V supply range covers the nominal 12V automotive battery voltage with headroom for load-dump transients.

Package and layout — 8-HVSON exposed pad

The 8-HVSON package measures 3x3 mm with an exposed pad underneath. That pad must be soldered to a PCB thermal land and, ideally, connected to a ground plane via thermal vias to pull heat out of the die. Without that thermal management, the junction temperature will rise faster under load, eating into the 150°C margin. The supplier device package is designated 8-HVSON (3x3), so the footprint matches standard 8-pin DFN patterns with a center pad.

Lifecycle and sourcing

The part is ROHS3 compliant.

Frequently asked questions

Is TJA1027TK/20,118 compatible with 3.3V microcontrollers?

The TJA1027TK/20,118 is a LIN transceiver with a supply range of 5V to 18V. Its logic-level interface is designed for the LIN protocol controller, typically running at the same supply voltage or a regulated 5V/3.3V domain — but the evidence does not specify the logic-level thresholds, so verify the VIH/VIL against your MCU's I/O voltage in the datasheet.

What is the closest pin-compatible alternative to TJA1027TK/20,118?

The TJA1027 family includes several package and temperature variants (e.g., TJA1027T/20 for the SO-8 package). The TK/20 suffix specifies the 8-HVSON package and the -40°C to 150°C temperature grade. For a pin-compatible alternative, look at other TJA1027 derivatives in the same 8-HVSON footprint — the pinout is consistent across the family, but confirm the temperature grade and supply range match your requirements.
