FAQ

What is the function of the inverted register enable?

The inverted register enable controls the latching of data into the internal registers, allowing for specific timing and control logic configurations in the circuit design.

How does the device handle power-up and power-down states?

To ensure a high-impedance state during power transitions, the OE pin should be tied to VCC through a pullup resistor, supporting live insertion capabilities.
