Description
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
CE. When LOW, selects the chip. When HIGH, deselects the chip
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
GND. Ground for the device
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.
