Automotive-grade I²C/SMBus level shifting
For designs requiring 125°C capability, a part like the SN74LXC2T45DTTR extends the range but lacks the AEC-Q100 automotive qualification this part carries.
Package and footprint for space-constrained PCBs
Housed in an 8-VFSOP package (2.30 mm width, 0.091" body) also designated as 8-VSSOP in the supplier device package field, this is a compact surface-mount part suited for dense automotive PCB layouts where every square millimeter counts. The mounting type is surface mount, standard for automated assembly lines. No thermal pad concerns — the part's low quiescent current keeps dissipation minimal.
The base product number PCA9306 spans both commercial and automotive variants; the Q1 suffix specifically denotes AEC-Q100 qualification.
