TCA9801DGKR TI I2C Buffer | 8-VSSOP | 2-Wire Bus, Hot-Swap

Product Overview

The TCA9801DGKR from Texas Instruments is a high-performance I2C bus buffer designed to extend the I2C bus capacitance and enable hot-swap capability. Housed in a compact 8-VSSOP package, it provides bidirectional voltage-level translation (1.65V to 5.5V) and supports standard (100 kHz) and fast-mode (400 kHz) I2C operations. This device is ideal for applications requiring robust bus buffering, such as telecommunications, industrial control, and automotive systems.

Detailed Technical Specifications

Key Features

• Bidirectional voltage-level translation between 1.65V and 5.5V
• Hot-swap capability without glitches on the bus
• Supports standard and fast-mode I2C
• Low standby current (0.1 µA typical)
• High ESD protection (8 kV HBM)
• Small 8-VSSOP package for space-constrained designs

Target Applications

• 5G base stations: buffering I2C signals between baseband and RF modules
