This 8-bit noninverting translator uses two separate configurable power-supply rails.The A port is designed to track V CCA .V CCA accepts any supply voltage from 1.2V to 3.6V.The B port is designed to track V CCB .V CCB accepts any supply voltage from 1.65V to 5.5V.This allows for low-凯里
学院学报 voltage bidirectional translation between any of the 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 placed in the high-impedance state.
To ensure the high-impedance state during power up or power down,OE should be tied to GND through a pulldown resistor;the minimum value of the resistor is determined by the current-sourcing capability of the driver.
