This eliminates the direction pin found on many level translators (e.g., the SN74LXC2T45 family), saving a microcontroller GPIO and simplifying the firmware state machine. The pass-gate architecture also allows the output type to be either open-drain or push-pull, so it works with I2C's wired-AND bus as well as standard CMOS push-pull signals. Housed in an 8-VFSOP (2.30 mm width) package, also designated as supplier device package 8-VSSOP. The 0.5 mm pin pitch demands a controlled solder-paste stencil and a reflow profile appropriate for MSL 1 (per TI's standard handling). The compact footprint suits space-constrained designs like sensor modules, portable instruments, and interface dongles. ROHS3 compliant. No known PCN affecting the DCUR (VSSOP-8) package variant.","metaTitle":"PCA9306DCUR Bidirectional Voltage-Level Translator","metaDescription":"TI PCA9306DCUR bidirectional voltage-level translator, 2-channel, auto-direction sensing.
