FXLA108 Datasheet | onsemi

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 3.6 V to as low as 1.1 V. 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: 1.2 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 = 0 V, 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 FXLA108 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. Features - Bi- Directional Interface Between Two Levels: from 1.1 V to 3.6 V - 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 on A or B Ports - 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 k V HBM (per JESD22- A114 &Mil Std 883e 3015.7) - 2 k V CDM (per ESD STM 5.3) - This is a Pb- Free Device Applications - Laptops, Notebooks - Routers, Switches WQFN20 4.5x2.5, 0.5P CASE 510CD MARKING DIAGRAM $Y&Z&2&K FXLA108 $Y &Z &2 &K FXLA108 = Logo = Assembly Plant Code = 2- Digit Date Code = 2- Digits Lot Run Traceability Code = Specific Device Code ORDERING...
