FAQ

What is the maximum propagation delay time?

The maximum propagation delay time (tpLH/tpHL) is 0.25 ns when measured under standard test conditions.

How does the output enable pin control the switch?

When the Output Enable (OE) pin is at a High level, the switch connects the A port to the B port. When OE is Low, the switch disconnects the ports.

What is the typical on-resistance of the switch?

The typical on-resistance (RON) is 5 Ω, measured at a supply voltage of 5 V and room temperature.
