Working Principles

The TXS0104EQPWRQ1 is a bidirectional level shifter that enables communication between devices operating at different voltage levels. It utilizes a voltage translation technique to convert signals from one voltage domain to another. The device has four channels, each capable of translating signals bidirectionally.

The input voltage range on the A side (VCCA) can be as low as 0V and as high as VCCA. Similarly, the input voltage range on the B side (VCCB) can be as low as 0V and as high as VCCB. The device translates these input voltages to the desired output voltage range on the respective sides.

The TXS0104EQPWRQ1 also features an output enable pin (OE) that allows the user to disable the outputs when needed.
