To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

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 VCCB level. This allows for bi-directional voltage translation over a variety of voltage The device remains in 3-state until both VCC 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 VCC is removed. The OE input, when low, disables both A and B ports by placing them in a 3-stat e condition. The FXL2SD106 is designed so that OE and CLK IN are supplied by VCCA. 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.

This benefit derives from the chip design. When either VCC is at 0 volts, outputs are in a high-impedance state. Th e control input (OE) is designed to track the V CCA supply. A pull-down resistor tying OE to GND should be used to ensure that bus con- tention, excessive currents, or oscillations do not occur during power-up / power-down. The size of the pull-down resistor is based upon the current-sinking capability of the device driving the OE pin. The recommended power-up sequence is the following: 1. Apply power to the first VCC. 2. Apply power to the second VCC. 3. Drive the OE input high to enable the device. The recommended power-down sequence is the following: 1. Drive OE input low to disable the device. 2. Remove power from either VCC. 3. Remove power from other VCC. Number Name Description 1V CCA A-Side Power Supply

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. Note: 1. IO Absolute Maximum Rating must be observed. Recommended Operating Conditions(2) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings.
