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 absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease 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 reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

TC7WPN3125FK General Description
The TC7WPN3125 is a dual supply, advanced high-speed CMOS 2-bit dual supply voltage interface bus buffer fabricated with silicon gate CMOS technology. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V.
Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V,or 2.5-V bus and a 1.8-V, 2.5-V or 3.6-V bus in mixed 1.2-V, 1.5-V, 1.8-V or 2.5-V/1.8-V, 2.5-V or 3.6-V supply systems.The A-input interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus, the B-output with the 1.8-V, 2.5-V, 3.3-V bus.
The enable input (OE) can be used to disable the device so that the signal lines are effectively isolated.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease 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 reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: Don't supply a voltage to VCCB pin when VCCA is in the OFF state. Note 3: Output in OFF state Note 4: High or Low stats. IOUT absolute maximum rating must be observed.
