An Introduction of TXS0108EPWR Level Shifter

Introduction

The TXS0108EPWR is an eight-bit non-inverting level shifter. It is able to use two distinct adjustable power rails. The A port is used to monitor the VCCA pin's supply voltage. VCCA pins are able to accept any voltage that is between 1.4V to 3.6V. Port B tracks the VCCB supply voltage for the pin. When the output-enable output is at a low level the outputs are all being in the high-impedance condition. To ensure Hi-Z status at power-on and power-off it is connected OE to GND through a pull-down resistor. The minimal resistivity is determined by the power source capabilities that the driver has.

Where to Use TPS54331DR?

Level shifters are very popular when designing circuits. Because doing circuit design is like building blocks. Different circuit modules are put together to create an electronic item. Inconsistent voltage domains often occur between circuit modules. Thus, communications between the modules should make use of a TPS54331DR switcher circuit for level shifting.

For instance, when a module is communicating via the I2C bus there are devices using devices that use the 3.3V voltage domain as well as devices that use the 5V domain, which is connected to the bus. It is the expression used to refer to the logarithm that represents the ratio of two voltages or two powers or voltages. It can use to represent the logarithm of the ratio between two currents. The decibel value that is used to measure the amount is calculated in decibels. There are two kinds of levels that are commonly used, voltage level and power level. Each is divided by absolute level or relative level.

How to Use TPS54331DR?

1. If the level shifter is equipped with no mechanism to pull back the bus line and it is the "low voltage" portion that is the bus line gets increased to 3.3V by the pull-up resistor Rp. The gate and the source of the MOS-FET tube both are 3.3V and therefore its VGS is less than its threshold voltage and the MOSFET tube does not conduct. This permits to allow the "high voltage" portion of the bus line towards 5V by its pull-up resistor Rp.

2. If an 3.3V device draws into the bus line until an unsatisfactory level The MOS-FET tube's source will also be a low level. The gate voltage is 3.3V. VGS increases above the threshold, and the MOSFET tube begins to conduct. The "high voltage" section that is the bus line gets lowered to a lower level through the 3.3V device via the conducting MOS-FET tube.

3. If a device with 5V draws down the bus line to a lower level The "low voltage" component of the diode draining from the MOS-FET tube gets drawn down until VGS reaches the threshold. The MOSFET tube then begins to conduct. This is also known as the "low voltage" section of the line brought down to a low niveau by the 5V device, which is then inserted into the MOS-FET tube which conducts.
