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.

Note: Exceeding any of the absol ute maximum ratings, even briefly, lead to deter ioration in IC performance or even

destruction.

Using continuously under h eavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decreas e in the reliability significantly even if

the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum

ratings and the operating ranges.

Please design the appropriate reliabil ity upon reviewing the Toshiba Semic onductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).

Figure 1 Application Circuit Diagram

The voltage difference between the (low-voltage) VCCA system and the (high-voltage) VCCB system must be 0.5

V or greater. (VCCA < VCCB)

For level-shifting between the VCCA and VCCB systems, connect a bias resistor between the VH pin and the

VCCB system, and also connect pull-up resistors to An and Bn pins.
