1.2V to 3.6V Universal Bidirectional Level Shifter
with Automatic Direction Control
Features
Description
 PI4ULS3V08 is designed for low voltage
operation: 1.2V to 3.6V
 Universal bidirectional level shifting with
automatic direction control
 Fast bus speeds up to 180 Mbps for push-pull
application
 Drive Capability 12mA
 Independent translation of each bit
 Each supply rail is configurable over supply range
 ESD Protection exceeds JESD22
 2000V Human Body Model (A114-B)
 200V Machine Model (A115-A)
 Latch-up performance exceeds 100mA per JESD
78
 Industrial operation at -40°C to +85°C
 Package: 36-contact TQFN 5x6
PI4ULS3V08, is a 8-bit (dual-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 xOE, xSEL, TEST_EN and
OUT_SEL are supplied by VCCB.
To ensure the high impedance state during power-
Pin Configuration
up or power- down, the output-enable (OE) input should
be tied to VCC through a pull-up 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 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.
