LXS0204L

Description

The LXS0204/LXS0204L is a 4-bit, configurable, dual-supply, bidirectional, auto-sensing translator that does not require a directional control pin. The A and B ports are designed to track two different power supply rails, V_CCA and V_CCB respectively. The V_CCA supply rail is configurable from 0.72V to 1.98V. The V_CCB supply rail is configurable from 1.65V to 5.5V. This allows voltage logic signals on the V_CCA side to be translated into higher or equal value voltage logic signals on the V_CCB side.

The translator has integrated 10kΩ pullup resistors on the Port A lines and Port B lines for up to 150 pF loading. The integrated pullup resistors are used to pull up the I/O lines to either V_CCA or V_CCB.

Port A and OE are referenced to V_CCA and port B is referenced to V_CCB. A LOW level at pin OE causes all I/Os to be a high-impedance OFF-state. Power-off protection is implemented to prevent the current from passing through the device when it is powered down.

The LXS0204/LXS0204L is an excellent match for open-drain applications such as the I2C communication bus. For push-pull applications, the LXS0204L disables the internal pullup resistors during logic-low and re-enables the internal pullup resistors during logic-high, thereby reducing static power consumption.
