FXLA108
Low-Voltage Dual-Supply 8-Bit Voltage Translator with
Configurable Voltage Supplies and Signal Levels,
3-State Outputs, and Auto Direction Sensing
Features
ƒ Bi-Directional Interface between Two Levels:
from 1.1V to 3.6V
ƒ Fully Configurable: Inputs and Outputs Track VCC
ƒ Non-Preferential Power-Up; Either VCC May Be
Powered Up First
ƒ Outputs Remain in 3-State Until Active VCC Level is
Reached
ƒ Outputs Switch to 3-State if Either VCC is at GND
ƒ Power-Off Protection
ƒ Bus-Hold on Data Inputs Eliminates the Need for
Pull-Up Resistors
ƒ Control Input (/OE) Referenced to VCCA Voltage
ƒ Packaged in 20-Terminal DQFN (2.5mm x 4.5mm)
ƒ Direction Control Not Necessary
ƒ 100Mbps Throughput when Translating Between
www.DataSheet41U..8cVomand 2.5V
ƒ ESD Protection Exceeds:
- 8kV HBM
(per JESD22-A114 &Mil Std 883e 3015.7)
- 2kV CDM (per ESD STM 5.3)
Description
The FXLA108 is a configurable dual-voltage supply
translator for both uni-directional and bi-directional
voltage translation between two logic levels. The device
allows translation between voltages as high as 3.6V to
as low as 1.1V. The A port tracks the VCCA level and the
B port tracks the VCCB level. This allows for bi-directional
voltage translation over a variety of voltage levels: 1.2V,
1.5V, 1.8V, 2.5V, and 3.3V.
The device remains in three-state until both VCCs reach
active levels, allowing either VCC to be powered up first.
Internal power-down control circuits place the device in
3-state if either VCC is removed.
The /OE input, when HIGH, disables both the A and B
ports by placing them in a 3-state condition. The /OE
input is supplied by VCCA.
The FXLA108 supports bi-directional translation without
the need for a direction control pin. The two ports of the
device have auto-direction sense capability. Either port
may sense an input signal and transfer it as an output
signal to the other port.
Applications
ƒ Laptops, Notebooks,
ƒ Routers, Switches

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
