Input/Control Chip Enable input, active LOW. When LOW, selects the chip. When
HIGH, deselects the chip.
31
37
Input/Control Output Enable, active LOW. Controls the direction of the I/O pins.
When LOW, the I/O pins are allowed to behave as outputs. When
deasserted HIGH, I/O pins are three-stated, and act as input data pins.
