This device is an 8-bit non-inverting level translator that uses two separateconfigurable power-supply rails. The A port tracks the VCCA pin supplyvoltage. The VCCA pin accepts any supply voltage between1.4 V and 3.6 V. The B port tracksthe VCCB pin supply voltage. The VCCB pin accepts anysupply voltage between 1.65 V and 5.5 V. Two input supply pins allows for low Voltage bidirectionaltranslation between any of the 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(Hi-Z) state.
To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through apull-down resistor. The minimum value of the resistor is determined by the current-sourcingcapability of the driver.
