Description
PI4ULS3V08, is a 8-bit (octal) non-inverting bus
transceiver with two separate supply rails: A port (VCCA)
and B port (VCCB) are set to operate at 1.2V to 3.6V. This
arrangement permits universal bidirectional translation of
differential signal levels over the voltage ranges.
The PI4ULS3V08 is designed for asynchronous communication
between data buses. Data is transmitted from the A bus to the B
bus, or vice versa, without direction control. All AX, and BX are
tri-stated when data is coming from both directions at the same
time. The output-enable (OE) input is used to disable outputs so
buses are isolated.
The control pins, xSEL, OEx, TEST_EN and OUT_SEL are
supplied by VCCB.
To ensure the high impedance state during power-up or power-
down, the output-enable (OE) input should be tied to VCC through
a pullup resistor: the minimum value of the resistor is determined
by the current-sinking capability of the driver.

Note:
1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 3.6V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
4. 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 conditions above those indicated in the operational sections of this specication is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
