Features

•

The TC7WPB306 and TC7WPB307 are high-speed CMOS

These devices have two separate power supplies, VL for a 1.8-V,

For bidirectional level-shifting, the VH pin is connected to a

The enable signal can be used to disable the device so that the

For the TC7WPB306, Output Enable (OE) is active-High: When

The TC7WP306 and TC7WP307 support power-down protection

The bus switch channels are fabricated with NMOS technology.

All inputs are equipped with protection circuits against static
