This one-bit non-inverting translator uses two separate configurable power-supply rails.
The A port is designed to track VCCA. VCCA accepts
any supply voltage from 1.65 V to 3.6 V. The B port is designed to track
VCCB. VCCA must be less than or equal to
VCCB. VCCB accepts any supply voltage from 2.3 V to
5.5 V. This allows for low voltage bidirectional translation between any of the 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
To ensure the high-impedance state during power up or power down, OE should be tied to
GND through a pull-down resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
