FXMAR2102 - Fairchild Semiconductor

FXMAR2102 2-Bit Voltage Translator / Isolator

The FXMAR2102 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels. The FXMAR2102 also works in a pushpull environment. It is intended for use as a voltage translator between I2C-Bus® compliant masters and slaves. Internal 10KΩ pull-up resistors are prov.
