Frequently Asked Questions
How do I ensure high impedance during power up or down?
OE should be tied to V through a pull-up resistor to guarantee the high-impedance state during power cycling.
What signal voltages can this buffer safely interface with?
It is optimized for low voltage (2.5V or 3.3V), but features are tolerant of 5V signals and supports up to 5V inputs and outputs.
How does the output control work across all 16 bits?
The device uses nibble-controlled architecture, allowing individual buffers to be controlled, or they can be shorted together for full 16-bit operation.
