Pin Definitions
Input
A0-A16. Address Inputs
Input/Output
I/O0-I/O7. Data lines. Used as input or output lines depending on operation
Input/Control
WE. Write Enable, Active LOW. When selected LOW, a WRITE is conducted. When selected HIGH, a READ
is conducted.
Input/Control
CE1. Chip Enable 1, Active LOW.
Input/Control
CE2. Chip Enable 2, Active HIGH.
Input/Control
OE. Output Enable, Active LOW. Controls the direction of the I/O pins. When LOW, the I/O pins behave as
outputs. When deasserted HIGH, I/O pins are three-stated, and act as input data pins
Ground
GND. Ground for the device
Power Supply
VCC. Power supply for the device
Notes:
2. Typical values are included for reference only and are not tested or guaranteed. Typical values are an average of the distribution across normal production
variations as measured at VCC = 5.0V, TA = 25°C, and tAA = 70 ns.
