Features
Description
Bi-Directional Interface between Two Levels:
from 1.1V to 3.6V
Fully Configurable: Inputs and Outputs Track VCC
Outputs Switch to 3-State if Either VCC is at GND
Control Input (/OE) Referenced to VCCA Voltage
Direction Control Not Necessary
ESD Protection Exceeds:
- 8kV HBM (per JESD22-A114 & Mil Std 883e
3015.7)
- 2kV CDM (per ESD STM 5.3)
Non-Preferential Power-Up; Either VCC May Be
Powered Up First
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
Available in 16-Terminal UMLP (1.8mm x 2.6mm)
and 12-Terminal, Quad UMLP, 1.8 x 1.8mm
Packages
100Mbps Throughput when Translating Between
1.8V and 2.5V
The FXLA104 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 as long as either
VCC=0V, 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 FXLA104 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.

Functional Diagram
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.
