| Part Number | TCA9517ADGKR |
|---|---|
| Manufacturer | Texas Instruments Incorporated |
| Category | Integrated Circuits (ICs) > Interface > I2C/SMBus Repeaters, Buffers & Extenders |
| Description | 1-CHANNEL I2C/SMBUS SIGNAL REPEATER, 1.65V TO 5.5V, 400KHZ, -40 TO 85 DEG C, 8-VSSOP |
Product Overview
The TCA9517ADGKR is a single-channel I2C and SMBus signal repeater from Texas Instruments, designed to extend bus length, boost signal integrity, and enable mixed-voltage communication in embedded systems. This device buffers bidirectional I2C/SMBus signals, allowing isolation between low-voltage logic (1.65V to 3.3V) and higher-voltage bus lines (up to 5.5V), while supporting clock frequencies up to 400kHz for fast-mode operation. With automatic direction sensing and no external control signals required, the TCA9517ADGKR simplifies system design and improves noise immunity in long bus configurations. It features low standby current, over-temperature protection, and lock-up prevention for reliable operation. Packaged in a compact 8-VSSOP form factor and operating across -40°C to +85°C, this repeater is ideal for industrial, automotive, and consumer electronics requiring robust I2C/SMBus signal extension and voltage translation.
