FXLA102  
Low-Voltage Dual-Supply 2-Bit Voltage Translator with  
Configurable Voltage Supplies and Signal Levels,  
3-State Outputs, and Auto Direction Sensing  
Features  
Description  
.
.
.
Bi-Directional Interface between Two Levels:  
from 1.1V to 3.6V  
The FXLA102 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.  
Fully Configurable: Inputs and Outputs Track VCC  
Level  
Non-Preferential Power-Up; Either VCC May Be  
Powered Up First  
.
.
.
Outputs Switch to 3-State if Either VCC is at GND  
Power-Off Protection  
The device remains in three-state as long as either  
VCC=0V, allowing either VCC to be powered up first.  
Bus-Hold on Data Inputs Eliminates the Need for  
Pull-Up Resistors; Do Not Use Pull-Up Resistors on  
A or B Ports  
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

Control Input (/OE) Referenced to VCCA Voltage  
Packaged in MicroPakTM 8 (1.6mm x 1.6mm)  
Direction Control Not Necessary  
input is supplied by VCCA  
.
The FXLA102 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.  
100Mbps Throughput when Translating Between  
1.8V and 2.5V  
.
ESD Protection Exceeds:  
- 15kV HBM ((B Port I/O to GND) per JESD22-  
A114 & Mil Std 883e 3015.7)  
- 8kV HBM ((A Port I/O to GND) per JESD22-A114  
& Mil Std 883e 3015.7)  
- 2kV CDM (per ESD STM 5.3)
