Product details

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.

Frequently asked questions

Is PCA9306IDCURQ1 automotive grade?

Yes, the PCA9306IDCURQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive applications per the AEC-Q100 stress test qualification for integrated circuits.

What is the difference between PCA9306IDCURQ1 and PCA9306DCUR?

The PCA9306IDCURQ1 carries AEC-Q100 automotive qualification (the Q1 suffix), while the PCA9306DCUR is the commercial-grade variant without automotive certification. Both share the same base PCA9306 voltage-level translator function and bidirectional auto-direction sensing.

Does PCA9306IDCURQ1 require external resistors?

As a bidirectional open-drain translator, the PCA9306IDCURQ1 typically requires external pull-up resistors on both the VCCA and VCCB buses to set the logic-high voltage levels, consistent with standard I²C/SMBus level-shifting practice.

Does PCA9306IDCURQ1 come in a reel?

Yes, the PCA9306IDCURQ1 is available in Tape & Reel (TR) packaging, as well as Cut Tape (CT) options for prototyping or smaller quantities.
