DATA SHEET www.onsemi.com Dual Supply, 2-Bit Voltage 2 Translator / Isolator for I C UQFN8, 1.4x1.2, 0.4P Applications CASE 523AS FXMAR2102 UQFN8 1.6X1.6, 0.5P Description CASE 523AY The FXMAR2102 is a high performance configurable dualvoltagesupply translator for bidirectional voltage translation MARKING DIAGRAM over a wide range of input and output voltages levels. The FXMAR2102 also works in a push pull environment. 2 BU&K It is intended for use as a voltage translator between I CBus &2&Z compliant masters and slaves. Internal 10 k pullup resistors are 1 provided. BU = Device Code The device is designed so the A port tracks the V level and the B CCA &K = 2Digits Lot Run Traceability Code port tracks the V level. This allows for bidirectional A/Bport CCB &2 = 2Digit Date Code voltage translation between any two levels from 1.65 V to 5.5 V. V CCA &Z = Assembly Plant Code can equal V from 1.65 V to 5.5 V. Either V can be poweredup CCB CC first. Internal powerdown control circuits place the device in 3state ORDERING INFORMATION if either V is removed. CC See detailed ordering and shipping information on page 13 of The two ports of the device have automatic directionsense this data sheet. capability. Either port may sense an input signal and transfer it as an output signal to the other port.
