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, VCCA
and VCCB respectively. Both the VCCA and VCCB supply
rails are configurable from 1.2V to 5.5V. This allows
voltage logic signals on the VCCA side to be translated
into lower, higher or equal value voltage logic signals on
the VCCB 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 VCCA or VCCB. The
PI4ULS5V202 is an excellent match for open-drain
applications such as the I2C communication bus.
