TCA9617A Description

Short technical summary and product information.

The TCA9617A is a dual-supply I2C bus buffer/repeater from Texas Instruments designed for level translation and signal buffering in I2C systems. It operates with VCCA from 0.8V to 5.5V and VCCB from 2.2V to 5.5V, allowing seamless interfacing between different voltage domains. The device supports I2C frequencies up to 1MHz, making it suitable for high-speed applications. It is housed in a compact VSSOP (DGK) package measuring 3mm x 3mm, ideal for space-constrained designs. The TCA9617A offers ESD protection of 4000V (HBM) and 1500V (CDM) and exceeds 100mA latch-up performance per JESD 78 Class II. It is a footprint and functional replacement for the TCA9517. The operating temperature range is -40°C to 85°C, ensuring reliable performance in industrial environments.
