The Texas Instruments PCA9306TDCURQ1 is a 2-channel bidirectional voltage level translator qualified to AEC-Q100, designed for automotive applications requiring logic-level translation between two voltage domains. Output type is open drain or push-pull, accommodating both wired-AND and standard push-pull topologies.
Because the part is bidirectional, the same two pins handle both transmit and receive — no extra GPIO for direction control. This simplifies layout on multi-voltage boards where an I2C bus crosses a voltage boundary.
Package and footprint — 8-VFSOP / 8-VSSOP
The PCA9306TDCURQ1 is supplied in an 8-VFSOP package (2.30 mm body width) and the supplier device package is 8-VSSOP. Both refer to the same ultra-small outline package with a 0.65 mm pitch, suitable for space-constrained automotive ECU boards. Surface-mount only. The tape-and-reel option (cut tape also available) aligns with high-volume pick-and-place assembly.
Temperature range — -45°C to 105°C
The extra margin at the cold end and the 105°C upper limit cover automotive cabin, engine-bay-adjacent, and outdoor telecom enclosures where ambient temperatures can spike. The AEC-Q100 qualification adds the stress-tested reliability expected for production automotive builds.
The part is ROHS3 compliant.
