The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

"WebOct 22, 2024 · When ESD occurs on a signal line and a TVS diode is present on the signal line, the diode will begin conducting and the pulse can pass through the diode. This allows the diode to divert the ESD pulse away from the protected circuit. The typical connection is to connect the anode to a ground connection, so the ESD pulse will be passed into ground.
