DATA SHEET www.onsemi.com Dual Supply, 2-Bit Voltage Translator / Buffer / UQFN8, 1.4x1.2, 0.4P 2 Repeater / Isolator for I C CASE 523AS Applications UQFN8 1.6X1.6, 0.5P FXMA2102 CASE 523AY Description MARKING DIAGRAM The FXMA2102 is a high performance configurable dualvoltagesupply translator for bidirectional voltage translation XN&K over a wide range of input and output voltages levels. &2&Z 2 Intended for use as a voltage translator between I CBus complaint 1 masters and slaves. XN = Device Code The device is designed so that the A port tracks the V level and CCA &K = 2Digits Lot Run Traceability Code the B port tracks the V level. This allows for bidirectional A/B CCB &2 = 2Digit Date Code port voltage translation between any two levels from 1.65 V to 5.5 V. &Z = Assembly Plant Code V can equal V from 1.65 V to 5.5 V. The OE pin is referenced CCA CCB to V . CCA ORDERING INFORMATION Either V can be poweredup first. Internal powerdown control See detailed ordering and shipping information on page 13 of CC this data sheet. circuits place the device in 3state if either VCC is removed. The two ports of the device have automatic direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port. Features BiDirectional Interface between Any Two Levels: 1.65 V to 5.5 V Direction Control not Needed System GPIO Resources Not Required when OE Tied to V CCA 2 I C 400 pF Buffer / Repeater 2 I C Bus Isolation A/B Port V = 175 mV (Typical), V = 150 mV, I = 6 mA OL IL OL OpenDrain Inputs / Outputs 2 Accommodates StandardMode and FastMode I CBus Devices 2 Supports I C Clock Stretching & MultiMaster Fully Configurable: Inputs and Outputs Track V CC Control Input (OE) Referenced to V CCA. NonPreferential PowerUp Either V May Be PoweredUp First CC Outputs Switch to 3State if Either V is at GND CC Tolerant Output Enable: 5 V Packaged in 8Terminal Leadless MicroPak (1.6 mm x 1.6 mm) and Ultrathin MLP (1.2 mm x 1.4 mm) ESD Protection Exceeds: 8 kV HBM ESD (per JESD22A114) 2 kV CDM (per JESD22 C101) Semiconductor Components Industries, LLC, 2010 1 Publication Order Number: August, 2021 Rev. 4 FXMA2102/DFXMA2102 BLOCK DIAGRAM OE V CCB Dynamic Driver (With Time Out) Internal Direction Generator & Ctrl VAV B bias bias A B V CCA Internal Direction Generator & Ctrl Dynamic Driver (With Time Out) Figure 1.
