FLXA108 — Low-Voltage Dual-Supply 8-Bit Voltage Translator March 2009 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 ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ Bi-Directional Interface between Two Levels: from 1.1V to 3.6V Fully Configurable: Inputs and Outputs Track VCC Non-Preferential Power-Up; Either VCC May Be Powered Up First Outputs Remain in 3-State Until Active VCC Level is Reached Outputs Switch to 3-State if Either VCC is at GND Power-Off Protection Bus-Hold on Data Inputs Eliminates the Need for Pull-Up Resistors Control Input (/OE) Referenced to VCCA Voltage Packaged in 20-Terminal DQFN (2.5mm x 4.5mm) Direction Control Not Necessary 100Mbps Throughput when Translating Between 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 de...
