AN10441 2 Level shifting techniques in I C-bus design Rev. 01 18 June 2007 Application note Document information Info Content Keywords I2C-bus, level shifting Abstract Logic level shifting may be required when interfacing legacy devices with newer devices that use a smaller geometry process. For bidirectional bus 2 systems like the I C-bus, such a level shifter must also be bidirectional, without the need of a direction control signal. The simplest way to solve this problem is by connecting a discrete MOS-FET to each bus line.AN10441 NXP Semiconductors 2 Level shifting techniques in I C-bus design Revision history Rev Date Description 01 20070618 Application note initial version.
