This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing.
This 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 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. 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 should not exceed VCCB. We have broken out each pin on this module for you to easily access both the A and B ports.
Features:
- 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-μA Max ICC

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- High-impedance
- Impedance is the opposition a circuit presents to current, so high-impedance means very little current flows. The term covers both a high-impedance input or node, which can sense a voltage without drawing it down (so very large resistors such as 10 megaohms are common), and the high-impedance (Hi-Z) state of a tri-state output, where a pin is effectively disconnected so other devices can drive a shared line.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
