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 1.2V to 3.6V. VCCA may be greater than

or equal to VCCB as long as VCCA is less than 3.6V.

The B port is designed to track VCCB. VCCB accepts

any supply voltage from 1.65V 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.
