TCA9800DGKT TI I2C Buffer | 8-VSSOP | 2-Wire Bus, Hot-Swap

Product Overview

The TCA9800DGKT from Texas Instruments is a dual bidirectional I2C buffer and voltage level translator designed for 2-wire bus applications. It provides buffering for both the serial data (SDA) and serial clock (SCL) lines, enabling communication between devices operating at different voltage levels (0.9V to 5.5V on the A side and 2.5V to 5.5V on the B side). The device supports hot-swap capability, allowing insertion or removal of cards without disrupting the bus. Packaged in a compact 8-VSSOP, it is ideal for space-constrained designs.
