TTL logic require boards to operate on 5V logic levels which is fairly standard for old microcontrollers and development boards. Even today most of the sensor, development boards and digital circuits run on 5V power supply to easily incorporate them in other circuits without any need of voltage shifting. But today with the advent of CMOS technology most of the microcontrollers work on 3.3V logic Levels which has certain merits like low power dissipation, faster switching action and high reliability. This 8 channel Bi Directional Logic level converter module is used to switch the 3.3V logic signals to 5V logic signals and vice versa. It is very helpful us using old sensors circuitry easily with newer 3.3V much more powerful boards like Nano, BeagleBone Black, Raspberry Pi etc.
TXS0108E 8-Channel Logic Level Converter Module Specifications
- Voltage levels 1.8V to 6V
- 8 Channels for connecting 8 different lines for their logic level conversion
- Bi directional so no need for additional control inputs
- Small in size
To use this module ensure that the two power supplies are common grounded and connect that common terminal to the GND Pin on the Module. Connect VCC-A to 3.3V Power Supply and VCC-B to 5V Power Supply. As it is bidirectional there is no need to give directional inputs to it.
