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 tristated, 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.
