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 3.6 V to as low as 1.1 V. The A port tracks the V
level and
CCA
FXLA108 = Specific Device Code
the B port tracks the V
level. This allows for bi−directional voltage

translation over a variety of voltage levels: 1.2 V, 1.5 V, 1.8 V, 2.5 V,
and 3.3 V.
ORDERING INFORMATION
See detailed ordering and shipping information on page 15 of
this data sheet.
The device remains in three−state as long as either V = 0 V,
CC
allowing either V to be powered up first. Internal power−down
CC
control circuits place the device in 3−state if either V is removed.
CC
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
V
CCA
.
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.
Features
• Bi−Directional Interface Between Two Levels: from 1.1 V to 3.6 V
• Fully Configurable: Inputs and Outputs Track V
CC
• Non−Preferential Power−Up; Either V May Be Powered Up First
CC
• Outputs Switch to 3−State if Either V is at GND
CC
• Power−Off Protection
• Bus−Hold on Data Inputs Eliminates the Need for Pull−Up Resistors;
Do Not Use Pull−Up Resistors on A or B Ports
• Control Input (/OE) Referenced to V
Voltage
CCA
• Packaged in 20−Terminal DQFN (2.5 mm x 4.5 mm)
• Direction Control Not Necessary
• 100 Mbps Throughput when Translating Between 1.8 V and 2.5 V
• ESD Protection Exceeds:
♦ 8 kV HBM (per JESD22−A114 &Mil Std 883e 3015.7)
♦ 2 kV CDM (per ESD STM 5.3)
• This is a Pb−Free Device
Applications
• Laptops, Notebooks
• Routers, Switches

I/O ARCHITECTURE BENEFIT
The FXLA108 I/O architecture benefits the end user,
beyond level translation, in the following three ways:
only the bus hold drives the channel. The bus hold can be
over ridden in the event of a direction change. The strong
driver allows the FXLA108 to quickly charge and discharge
capacitive transmission lines during dynamic mode. Static

current drive mode only during “Dynamic Mode” or HL /
LH transitions.
mode conserves power, where I is typically < 5 mA.
CC
Bus Hold Minimum Drive Current
Specifies the minimum amount of current the bus hold
driver can source/sink. The bus hold minimum drive current

low−power mode during “Static Mode” (no transitions),
lowering power consumption.
(II
) is V
dependent and guaranteed in the DC
HOLD
CC
Electrical tables. The intent is to maintain a valid output state
in a static mode, but that can be overridden when an input
data transition occurs.
The FXLA108 does not require a direction pin. Instead,
the I/O architecture detects input transitions on both side and
automatically transfers the data to the corresponding output.
For example, for a given channel, if both A and B side are
at a static LOW, the direction has been established as A → B,
and a LH transition occurs on the B port; the FXLA108
internal I/O architecture automatically changes direction
from A → B to B → A.
During HL / LH transitions, or “Dynamic Mode,” a strong
output driver drives the output channel in parallel with a
weak output driver. After a typical delay of approximately
10 ns – 50 ns, the strong driver is turned off, leaving the weak
driver enabled for holding the logic state of the channel. This
weak driver is called the “bus hold.” “Static Mode” is when
