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,
VCCA and VCCB respectively. Both the VCCA and VCCB
supply rails are configurable from 1.1V to 3.6V. 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 PI4ULS3V204 is an excellent match for
open-drain applications such as the I2C communication
bus.
Applications
I2C, SMBus, MDIO
Low Voltage ASIC Level Translation
Mobile Phones, PDAs, Camera

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
