Input/Control
A0–A14. Address Inputs
I/O0–I/O7. Data lines. Used as input or output lines depending on operation
WE. When selected LOW, a WRITE is conducted. When selected HIGH, a READ is conducted
20
Input/Control CE. When LOW, selects the chip. When HIGH, deselects the chip
22
Input/Control OE. Output Enable. Controls the direction of the I/O pins. When LOW, the I/O pins behave as
outputs. When deasserted HIGH, I/O pins are tri-stated, and act as input data pins
14
Ground
GND. Ground for the device
28
Power Supply VCC. Power supply for the device
Note:
2. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC Typ., TA = 25°C, and tAA = 70 ns.
