Description
The PI4ULS3V204 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. Both the V_CCA and V_CCB
supply rails are configurable from 1.1V to 3.6V. 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 PI4ULS3V204 is an excellent match for
open-drain applications such as the I²C communication
bus.
