Auto-direction sensing means no DIR control pin is needed — the part determines direction from the bus state, which simplifies layout and firmware for open-drain buses like I²C or SMBus. ## Voltage range — what it covers and what it doesn't VCCA accepts 1.2 V to 3.3 V; The overlap means a 1.8 V logic master can talk to a 5 V peripheral, or a 3.3 V microcontroller to a 1.2 V sensor. The part does not translate below 1.2 V on the A side — if your design uses a 0.9 V core rail, you need a different translator. The output type supports both open-drain and push-pull, so it works with I²C (open-drain) and general-purpose push-pull signals. For automotive under-hood (125°C) you would look at a qualified part like the CAXC4T774QBQBRQ1. The 8-VSSOP (2.30 mm width) is a small footprint for space-constrained boards. Surface-mount only — no through-hole option.","metaTitle":"PCA9306DCUT Voltage Level Translator, 1.2V–5.5V","metaDescription":"Nexperia PCA9306DCUT bidirectional voltage-level translator.

The PCA9306DCUT uses auto-direction sensing, so the two are not drop-in replacements — the board design and firmware differ.
