The TC7MPB9307 is a CMOS 8-bit dual-supply bus switch that

The TC7MPB9307 can be connected to two independent power

Bidirectional level-shifting is possible by simply adding

The Output Enable ( OE ) input controls the connection or

The OE input is common for all the eight bits of the data

The TC7MPB9307 supports power-down protection at the OE

The channels consist of n-type MOSFETs.
