Overview

Description

TCA4311ADR is a Texas Instruments I2C-bus buffer/level shifter. It provides bidirectional buffering between two I2C buses (two channels), enabling voltage level translation and isolation between devices or subsystems. This helps extend I2C bus length, protect devices from noise or faults, and allow different logic voltages on each side. Typical uses include large or mixed-voltage I2C networks, hot-plug scenarios, and noisy environments where clean, separated I2C signaling is needed. The ADR suffix usually indicates a specific packaging/reel option. For exact electrical specs, pinout, voltage ranges, and mode behavior, consult the TI TCA4311ADR datasheet.

Package

8-pin small-outline package (MSOP-8 / VSSOP-8) surface-mount. Check the datasheet for exact body size.

Pinout

Pin count: 8 pins (available in VSSOP/SOIC style packages; part suffix ADR denotes package/ordering code).
Function (concise): TCA4311 is a bidirectional I2C/SMBus bus buffer/level translator. It connects two I2C buses operating at different supply voltages (VCCA and VCCB), providing level translation, bus-hold/pull-up support and power‑off isolation/ESD protection so a powered bus does not back‑drive an unpowered bus. Typical pins implement SDA_A/SCL_A, SDA_B/SCL_B, VCCA, VCCB, GND and an enable/reset/control pin (package pin names vary by datasheet).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and integrated circuits, specializing in analog, embedded processing, and digital signal processing products.

Application

- I2C bus buffering and level shifting between voltage domains
- Bus isolation to protect microcontrollers
- I2C line protection in automotive, industrial automation, and consumer electronics
- Extending I2C reach with additional devices
- Hardware-safe interfacing for hot-swappable I2C subsystems
