Dual Supply, 2-Bit Voltage
Translator / Buffer / Repeater / Isolator for I2C
Applications
UQFN8, 1.4x1.2, 0.4P CASE 523AS
FXMA2102
Description
The FXMA2102 is a high−performance configurable
dual−voltage−supply translator for bi−directional voltage translation
over a wide range of input and output voltages levels. Intended for use as a voltage translator between I2C−Bus complaint
masters and slaves.
The device is designed so that the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi−directional A/B port voltage translation between any two levels from 1.65 V to 5.5 V.
VCCA can equal VCCB from 1.65 V to 5.5 V. The OE pin is referenced to VCCA.
Either VCC can be powered−up first.
