Vue d'ensemble

Description

The TXB0108DQSR is an 8-channel bidirectional level-shifting transceiver designed to facilitate communication between devices operating at different voltage levels, typically between 1.2V and 5.5V. It is commonly used for I2C, SPI, and other serial communication protocols. The device features two supply voltage pins, allowing it to adapt to both high and low voltage sides seamlessly.
Key specifications include low propagation delays, high-speed operation up to 100 Mbps, and the ability to support multiple devices on the bus. The TXB0108DQSR is housed in a compact 20-pin TSSOP package, making it suitable for space-constrained applications.
One of its notable features is automatic direction sensing, which eliminates the need for direction control signals, simplifying circuit design. Its robust performance and versatility make it ideal for use in various applications, including microcontrollers, logic level interfacing, and sensor integration across different voltage domains.

Features

The TXB0108DQSR is an 8-channel bidirectional voltage-level translator, designed for interfacing between differing voltage levels, typically between 1.2V and 5.5V. Key features include:
- Bidirectional Operation: Facilitates communication between devices operating at different voltage levels without the need for direction control.
- Wide Supply Voltage Range: Supports VCCA and VCCB voltages from 1.2V to 5.5V, making it versatile for various applications.
- High-Speed Performance: Capable of supporting data rates up to 100 Mbps, suitable for fast communication needs.
- Low Power Consumption: Designed for energy efficiency, drawing minimal current during operation.
- Integrated Schmitt Trigger Inputs: Provides improved noise margins and ensures reliable switching at varying input levels.
- Compact Package: Offered in a 20-pin TSSOP package, facilitating easy integration into compact designs.
These features make the TXB0108DQSR ideal for applications in level shifting between microcontrollers, sensors, and other digital devices.

Package

The TXB0108DQSR is packaged in a 20-pin HTQFP (Thin Quad Flat Pack) package. This surface-mount package is designed for compact applications and facilitates easy integration into circuit boards.

Pinout

The TXB0108DQSR is an 8-channel bidirectional level shifter and has a pin count of 20. It is designed to interface between different voltage levels in digital circuits.
Pin Functions:
- Power Supply Pins: VCCA (for the low voltage side) and VCCB (for the high voltage side).
- I/O Pins: 8 pairs of I/O pins (A1-A8 for the low side and B1-B8 for the high side) facilitate bidirectional data transmission.
- Direction Control Pins: These are typically not needed for the TXB series as they automatically detect the direction of signal flow.
- GND Pins: Ground connections for circuit stability.
The TXB0108 operates in the range of 1.2V to 3.6V on VCCA and 1.65V to 5.5V on VCCB, making it suitable for interfacing various logic levels in systems like microcontrollers, sensors, and other digital devices.
