• The TXS0108EPWR is an 8 - bit non - inverting level translator. It uses two independent, 
• programmable power supply rails. The A port tracks the supply voltage of the VCCA pin, 
• which can accept any supply voltage between 1.4 V and 3.6 V. The B port tracks the supply voltage of the VCCB pin, 
• which can accept any supply voltage between 1.65 V and 5.5 V. 
• It enables low - voltage bidirectional translation between voltage nodes such as 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V, 
• facilitating communication between two systems with different levels.
• Automatic Direction Control: It features automatic direction control, 
• which can automatically identify the data transmission direction based on the input signal, 
• eliminating the need for external control signals. This simplifies the design and development process.
• High - Speed and Low - Power Consumption: It adopts Texas Instruments' Low - Voltage TTL (LVTTL) technology, 
• offering the advantages of high speed and low power consumption. Its static current is only 0.5 μA, which is very low2.
• Protection Functions: The TXS0108EPWR has various protection functions, such as short - circuit protection and over - current protection, 
• which can protect the circuit from damage2. In addition, 
• it has latch - up performance that exceeds 100 mA per JESD 78, 
• Class II, and built - in over - voltage and over - temperature protection circuits3.
• High - Impedance State: When the output - enable (OE) input is low, all outputs are put into the high - impedance (Hi - Z) state. 
• Tying OE to GND through a pull - down resistor ensures the Hi - Z state during power - up or power - down phases1.
