Product details

Bidirectional level shifter — now obsolete, sourced to order

The Texas Instruments PCA9306DCTRG4 is a single-circuit, 2-channel bidirectional voltage-level translator with auto-direction sensing. This part is officially marked as obsolete by Texas Instruments.

Voltage domains — what the VCCA and VCCB ranges mean for your design

The VCCA range of 1.2 V to 3.3 V covers the lower-voltage side. The part is bidirectional with auto-direction sensing, handling open-drain buses without a direction-control pin. The two channels per circuit translate two independent signals.

Package and footprint — 8-LSSOP/8-MSOP (SM8)

The package is an 8-lead LSSOP or MSOP with a 2.80 mm body width. The SM8 supplier device package is the TI designation for this footprint. It is a surface-mount package, so reflow soldering is standard.

Frequently asked questions

Can PCA9306DCTRG4 be used for I2C level shifting?

Yes. The PCA9306DCTRG4 is a bidirectional voltage-level translator with auto-direction sensing and supports open-drain output types, making it suitable for I²C bus level shifting. Its two channels per circuit map directly to the SDA and SCL lines.
