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 3.6 V to as low as 1.1 V. The A port tracks the VCCAlevel and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V

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. Bi-Directional Interface between Two Levels: from 1.1 V to 3.6 V

Features:

• Fully Configurable: Inputs and Outputs Track VCC
• 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
• Bus-Hold on Data Inputs Eliminates the Need for Pull-Up Resistors; Do Not Use Pull-Up Resistors
• Control Input (/OE) Referenced to VCCA Voltage
• Packaged in 20-Terminal DQFN (2.5 mm x 4.5 mm)
• Direction Control Not Necessary
• 100 Mbps Throughput when Translating Between 1.8 V and 2.5 V
• ESD Protection Exceeds:
• 8 kV HBM (per JESD22-A114 & Mil Std 883e 3015.7)
• 2 kV CDM (per ESD STM5.3)
