TCA39306DCUR Voltage Level Translator Bidirectional
The TCA39306DCUR is a dual-channel bidirectional voltage-level translator from Texas Instruments, specifically designed for seamless I2C and SMBus communication between devices operating at different voltage levels. It features an innovative auto-direction sensing architecture that requires no external directional control signal, simplifying system design. The device supports a wide voltage range on its two ports: Port A (VCCA) operates from 0.8V to 3.6V, and Port B (VCB) operates from 1.8V to 5.5V, enabling flexible translation between low-voltage processors and higher-voltage peripherals. It incorporates special circuitry to prevent bus lock-up and includes integrated pull-up resistors, making it a complete and robust solution for mixed-voltage I2C bus systems.
TCA39306DCUR Voltage-Level Translator Features and Specifications
This translator supports standard-mode (up to 100 kHz), fast-mode (up to 400 kHz), and fast-mode plus (up to 1 MHz) I2C clock frequencies. It is fully compliant with the I2C bus protocol, supporting clock stretching and multi-master arbitration. A key feature is its integrated 4.7 kΩ pull-up resistors on all I/O lines, which can be individually enabled or disabled via pin control, eliminating the need for external resistors. The device includes a static voltage offset feature to improve noise margin in low-voltage systems and offers robust 8-kV HBM ESD protection.
AlternativeVoltage-Level BufferModels
● NXP PCA9306: A popular dual bidirectional I2C-bus translator with an enable pin, known for its reliability and wide adoption in mixed-voltage systems.
● ON Semiconductor NTS0102: A dual-bit, configurable dual-supply translator supporting voltages from 1.2V to 5.5V, suitable for both I2C and general-purpose level shifting.
● Maxim Integrated (Analog Devices) MAX3390E: A dual-channel level translator with integrated pull-up resistors and enhanced ESD protection, designed for I2C and SMBus applications.
