FXL2SD106
Low-Voltage Dual-Supply 6-Bit Voltage
Translator with Auto-Direction Sensing
Features
– Bi-Directional Interface between Two Levels: 1.1V
and 3.6V
– Fully Configurable: Inputs and Outputs Track V_CC
Level
– Non-Preferential Power-up; Either V_CC May Be
Powered-up First
– Outputs Remain in 3-State until Active V_CC Level is
Reached
– Outputs Switch to 3-State if Either V_CC is at GND
– Power-Off Protection
– Bus hold on Data Inputs Eliminates Need for Pull-
up Resistors (Do NOT Use Resistors on the A or B
Ports)
– OE and CLK IN are Referenced to V_CCA Voltage
– Packaged in 16-Terminal DQFN (2.5mm x 3.5mm)
– Direction Control Not Needed
– 80 Mbps Throughput Translating between 1.8V
and 2.5V
– ESD Protection Exceeds:
– 12kV 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)
– 1kV CDM (per ESD STM 5.3)
General Description
The FXL2SD106 is a configurable dual-voltage-supply
translator designed 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 V_CCA
level and the B port tracks the V_CCB 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 3-state until both V_CC reach active
levels, allowing either V_CC to be powered-up first. Inter-
nal power-down control circuits place the device in 3-
state if either V_CC is removed.
The OE input, when low, disables both A and B ports by
placing them in a 3-state condition. The FXL2SD106 is
designed so that OE and CLK IN are supplied by V_CCA.
The device senses an input signal on A or B port auto-
matically. The input signal is transferred to the other port.
The FXL2SD106 is not designed for SD card applica-
tions. The internal bus hold circuitry conflicts with pull-up
resistors. SD cards have internal pull-up resistors on the
CD/DAT3 pins.
