PI4ULS5V202

Product Description

The PI4ULS5V202 is a 2-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. Both the V_CCA and V_CCB supply rails are configurable from 1.2V to 5.5V. This allows voltage logic signals on the V_CCA side to be translated into lower, higher or equal value voltage logic signals on the V_CCB side, and vice-versa.

The translator has integrated 10 kΩ pull-up resistors on the I/O lines. The integrated pull-up resistors are used to pull-up the I/O lines to either V_CCA or V_CCB. The PI4ULS5V202 is an excellent match for open-drain applications such as the I²C communication bus.
