Low Voltage/Low Power 2-Bit Dual Supply Bus Switch
The TC7WPB306 and TC7WPB307 are high-speed CMOS two-bit bus switches with low ON-resistance that allow interfacing between different voltage nodes.
These devices have two separate power supplies, VL for a 1.8-V, 2.5-V or 3.3-V bus and VH for a 2.5-V, 3.3-V or 5.0-V bus.
For bidirectional level-shifting, the VH pin is connected to a high-voltage power supply through a bias resistor, and pull-up resistors are connected between the high-voltage power supply and the switch.
The enable signal can be used to disable the device so that the buses are effectively isolated.
