3 Description

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 1.65V to 3.6V. VCCA must be less than or

equal to VCCB . The B port is designed to track VCCB.

VCCB accepts any supply voltage from 2.3V to 5.5V.

This allows for low voltage bidirectional translation

between any of the 1.8V, 2.5V, 3.3V, and 5V voltage

nodes.

When the output-enable (OE) input is low, all outputs

are placed in the high-impedance state.

To put the device in the high-impedance state during

power up or power down, tie OE to GND through

a pull-down resistor; the current-sourcing capability

of the driver determines the minimum value of the

resistor.
