3.3V 5V TXS0108E 8 Channel Logic Level Bi-directional Converter Module TXB0108 Mutual Convert Module TXS0108

Description

The module adopts TXS0108E chip, and this 8-bit in-phase converter uses two independent configurable power supplies. The A port is designed to track VCCA, which accepts any power supply voltage from 1.2 V to 3.6 V. The B-port is designed to track VCCB, which accepts any power supply voltage from 1.65 V to 5.5 V. This allows for low-voltage bidirectional conversion between any power source at 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. When the output enable (OE) input is low, all outputs are in a high impedance state. To ensure a high impedance state during power on or off, OE should use a pull-down resistor.

Product parameters

1. Using chips: TXS0108E

2. High speed full duplex 8-channel level conversion module

3. Provide bidirectional communication capability

4. Port A supports 1.2V to 3.6V, while Port B supports 1.65V to 5.5V (VCCA ≤ VCCB)

 

Product Application

1.5V microcontroller and 3.3V module, 3.3V microcontroller and 5V module, etc. Communication compatibility support

2. Level conversion for communication between microcontroller and SD card

3. Level conversion between microcontroller and I2C/SPI serial devices

Attention:

OE enables IO high level to be effective. It is recommended to connect the IO port at the low voltage end to ensure high impedance state during power on or off.

Simple usage method:

Install Arduino UNO、HW-221、Connect 8 light-emitting diodes and 1 1K resistor as shown in the diagram, and upload the program from the data to Arduino UNO. You can see that 8 LED lights are flashing
