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. |
