A1 - A8: These pins are for the low-voltage side of the level shifting channels. They handle the signal inputs/outputs from devices operating at lower voltages (e.g., 2.5V or 3.3V systems). B1 - B8: These pins are for the high-voltage side of the level shifting channels, and they handle signals from devices working at higher voltages (e.g., 5V systems). VCC and VCCA: These are the supply pins for the respective voltage sides of the device, ensuring proper voltage levels for the input/output signals. GND: Ground pins for both the low and high-voltage sides ensure the circuit has a common reference point.Circuit Principle
The TXB0104RUTR works by providing voltage level translation in a bidirectional manner, meaning that it can shift voltages in both directions. It features automatic direction sensing, which eliminates the need for an external control signal. This allows the chip to seamlessly work in systems where data might flow in either direction.
Key Features: Automatic bidirectional signal translation for multiple I/O channels. Voltage levels on either side can range from 1.2V to 5.5V. Low quiescent current when no signal is being translated. Suitable for applications like I2C, SPI, or other multi-wire data communication systems where components operate at different voltage levels.FAQ (Frequently Asked Questions)
