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
