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).
DescriptionThe TC7WPB306FK and TC7WPB307 are high-speed CMOS two-bit bus switches with low ON-resistance that allow interfacing between different voltage nodes.
The TC7WPB306FK has 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 TC7WPB306FK, Output Enable (OE) is active-High: When OE is High, the switch is on; when Low, the switch is off.
For the TC7WPB306FK, Output Enable (OE ) is active-Low: When OE is Low, the switch is on; when High, the switch is off. The TC7WPB306FK 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.
