TXS0108E Bi-directional Voltage Module

8-Bit High-Speed Bi-Directional Logic Shifting: Translates digital signal levels seamlessly across 8 independent channels without requiring a directional control (DIR) signal pin.

Dual Voltage Reference Power Rails (V_CCA & V_CCB): Supports flexible low-to-high and high-to-low logic conversion between 1.2 V - 3.6V (V_CCA) and 1.65V - 5.5V (V_CCB) rails.

Auto-Direction Sensing Architecture: Automatically detects signal transmission direction on the fly, simplifying interface routing between fast 3.3V and 5.0V integrated circuits.

High-Speed Data Throughput: Delivers reliable data transmission rates up to 60 Mbps (push-pull) or 2 Mbps (open-drain), making it ideal for SPI, I2C, and UART protocols.

Output Enable (OE) Power Saving Control: Features an active-high Output Enable pin to set outputs into high-impedance state for low-power idle modes.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with surface-mount TXS0108E logic converter IC and gold/tin-plated dual-row pin headers.

Technical Specifications:

Port A Voltage Range (V_CCA): 1.2V - 3.6V DC (Must be ≤ V_CCB).

Port B Voltage Range (V_CCB): 1.65 V - 5.5V DC.

Number of Channels: 8 Channels.

Color: Blue PCB with Surface-Mount Logic IC and Gold Pin Headers.

Usage Advice: Connect low-voltage logic (e.g., 3.3V) to V_CCA and higher-voltage logic (e.g., 5V) to V_CCB; ensure V_CCA voltage remains lower than or equal to V_CCB voltage and tie OE to V_CCA for normal operation.

Maintenance: Keep header pins straight and free from solder bridges; store and handle in anti-static packaging to prevent ESD damage.

Essential High-Speed Logic Level Shifter: Position as an indispensable interface module for bridging 3.3V microcontrollers (ESP32, Raspberry Pi, STM32) with 5V sensors, LCD displays, and legacy peripherals.

Highlight Auto-Directional 8-Channel Conversion: Emphasize how 8 simultaneous channels and auto-direction sensing streamline complex multi-pin bus connections (like SPI or parallel LCDs) without extra code or control pins.

Recommended Cross-Sell Add-ons: Pair with INA3221 Power Supply Voltage Monitor Board, AC Single Phase Voltage Transformer Sensor, Voltage Sensor Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
