Buffers, Drivers, Receivers, Transceivers FAQ

How are the output enable pins configured?

The device features two active-low output enable pins, OE1 and OE2. Both pins must be held low simultaneously for the outputs to become active; if either pin is high, the outputs enter a high-impedance state.

What is the function of the Ioff feature?

The Ioff feature disables all outputs when the supply pin is held at 0 V. This prevents damaging current from flowing back through the device's outputs into powered-down sections of the system.
