It is operational from 1.65 V to 3.6 V on A-Port and 2.3 V to 5.5 V on B-port. Enable (OE) input is referenced to VCCA with a maximum input voltage tolerance of 4.6 V. The TCA9406 can operate up to 24Mbps in push pull mode and 2Mbps with open drain mod. Its compatible with a standard I2C bus 100 kHz, 400 kHz and 1 MHz at both sides of A-Port and B-Port. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Copyright © 2010, Texas Instruments Incorporated TCA9406 SCPS221 – JULY 2010 www.ti.com With the standard I2C bus system, it needs pull-up resistors to provide logic HIGH levels on the translator bus. The TCA9406 is an open-drain bus level configuration of the I2C-bus. The value of pullup resistors depends on the system, but each side of the translator must have pull-up resistors and TCA9406 already has 10 kΩ pullup resistors on each side and it allows to add additional external pull-up resistors. It can work with standard-mode, fast-mode and fast mode plus I2C-bus devices in additional to SMBus. The TCA9406 is not a bus buffer like the PCA9515A and PCA9517. It provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The Ioff feature can be utilized to isolate the bus into high impedance when using the power supply to off the either VCCA or VCCB. The Enable (OE) should be tied to GND through a pulldown resistor to ensure the high-impedance state during power up or power down. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

an internal 10-kΩ pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-kΩ resistors). Adding lower value pullup resistors changes VOL levels. When the OE pin is set low, the internal pullups of the TCA9406 are disabled for power saving caused by pullup resistors. Figure 1. Typical Design Example The TCA6406 has a VCC isolation feature known as Ioff partial power down and backdrive protection. If a cable is connected, and the connected external system is still powered own, the system can be put into standby mode by shutting down the power rail. In this state, the TCA6406 has a leakage current of approximately 2 µA caused by current flow from powered-on system. Power Up, Power Down One advantage of the TCA9406 translator is that either power supply can be ramped up first. Another advantage is that either power supply can be set to 0 V, and the outputs are in high-impedance state. The recommended power up sequence is: 1. Apply power to the first VCC and apply the second VCC 2. Drive the OE input high to enable the device The recommended power down sequence is: 1. Drive OE input low to disable the device 2. Switch Off the power from either VCC and remove power from other VCC. Enable/Disable The TCA9406 han an OE input that is used to disable the device by setting OE low, which place all I/Os in the high-impedance state. The control OE is referenced to the VCCA supply. A pulldown resistor tying OE to ground should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power up and power down. The value of resistor is based upon the current sinking capability of the device. 10 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TCA9406 TCA9406 www.ti.com SCPS221 – JULY 2010 Integrated Pullup Resistors on the I/Os (A-Ports/B-Ports) Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-kΩ resistors). Adding lower value pull-up resistors may effect VOL levels, however. The internal pullups of the PCA9406 are disabled when the OE pin is low.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
