7Semi Bidirectional Voltage Level Translator Breakout TXB0104

7Semi TXB0104 board is a 4-bit bidirectional voltage-level translator with automatic direction sensing. It consists of Texas Instruments TXB0104 module. It features four channels of input/output signals and an output enable line that allows the signal lines to be placed in a high impedance mode when they are unneeded. 

This TXB0104 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA must not exceed VCCB. When the OE input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, OE must be tied to GND through a pulldown resistor The current sourcing capability of the driver determines the minimum value of the resistor. The TXB0104 device is designed so the OE input circuit is supplied by VCCA.

• 1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port (VCCA <= VCCB)
  
• VCC Isolation Feature - If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
  
• OE Input Circuit Referenced to VCC
  
• Low Power Consumption, 5-uA Max ICC

• A-side signals are the low voltage signals. VccA must be at a lower voltage than VccB. The voltage range for VccA is 1.2V to 3.6V.
• B-side signals are the high voltage signals. VccB must be at a higher voltage than VccA to avoid total protonic reversal (or at least, to avoid possible damage to the chip). The voltage range for VccB is 1.65 to 5.5V.

The bidirectional voltage-level translator breakout integrated with TXB0104 IC is a small electronic module that is designed to enable communication between devices that operate at different voltage levels. The module is equipped with a TXB0104 IC, which provides four bidirectional voltage level translations between two voltage domains. It also offers automatic direction sensing and +/- 15-kV electrostatic discharge (ESD) protection, ensuring safe and reliable data transfer. The breakout board form factor makes it easy to integrate with other electronic components, such as microcontrollers, sensors, and actuators, making it an essential component for electronics projects that require compatibility with different voltage levels. With its ability to translate between voltage domains bidirectionally, it is suitable for a wide range of applications, including embedded systems, robotics, and consumer electronics. The automatic direction sensing feature simplifies the integration process, while the ESD protection safeguards the module from electrostatic discharge, which can damage or destroy sensitive electronics components.

A bidirectional voltage level translator breakout is a small electronic module that is designed to enable communication between devices that operate at different voltage levels. It typically consists of a circuit that converts the voltage of the input signal to match the voltage of the output signal, allowing data to be exchanged between devices that would otherwise be incompatible. This breakout board is useful in a variety of applications where different components or modules may be operating at different voltage levels, such as in embedded systems, robotics, and consumer electronics. The bidirectional nature of the voltage level translator allows for communication in both directions, making it a versatile tool for a wide range of applications. Additionally, the breakout board form factor makes it easy to integrate with other electronic components, such as microcontrollers, sensors, and actuators, making it an essential component for electronics projects that require compatibility with different voltage levels.
