2-BIT BIDIRECTIONAL

VOLTAGE-LEVEL

TRANSLATOR FOR

OPEN-DRAIN AND PUSH-PULL

APPLICATIONS



DESCRIPTION

The UTC UVXS0102 is a two-bit non-inverting bidirectional

voltage-level translator and can be used to establish digital

switching compatibility between mixed-voltage systems.

The UTC UVXS0102 separates A ports with B ports, and both

ports are configurable power-supply rails, with the A ports

supporting operating voltages from 1.65V to 3.6V, and the B ports

supporting operating voltages from 2.3V to 5.5V. This allows the

support of both lower and higher logic signal levels while providing

bidirectional translation capabilities between any of the 1.8V, 2.5V,

3.3V, and 5V voltage nodes.

All I/Os of the UTC UVXS0102 are placed in the

high-impedance state when the output-enable (OE) input is low,

which significantly reduces the power-supply quiescent current

consumption. So, 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.
