Need information for level shifter

Hi,

I want to interface MCP3202 ADC (SPI Based ) and RTC1307 (I2C Based) with beagleboard Xm A3. But the 20 pin connector P11 & P13 has only 1.8V signal capacity. Any recommendation of low cost level shifter (1.8V <-> 3.3V) ?

Thnx in advance.

Regards,
Vishal

As alternative, as mentioned in the comments, TI TXB0108 and/or
TXS0108E might be better solution.
