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.
For the TC7WPB306, Output Enable (OE) is active-High: When
OE is High, the switch is on; when Low, the switch is off. For the
TC7WPB307, Output Enable ( OE ) is active-Low: When OE is
Low, the switch is on; when High, the switch is off.
The TC7WP306 and TC7WP307 support power-down protection
by incorporating 5.5-V-tolerant control inputs.
The bus switch channels are fabricated with NMOS technology.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
