PCA9306DCTTG4

Translators, Level Shifters Overview

The PCA9306DCTTG4 is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Texas Instruments. It operates with VCCA ranging from 1.0 V to 3.6 V and VCCB from 1.8 V to 5.5 V, enabling translation between 1.0 V and 5 V without direction control pins. The device features an enable input, low on-state resistance for minimal propagation delay, and open-collector outputs. It supports standard, fast, and fast-mode plus I2C protocols within an 8-pin SM package.
