Features
• High speed — 15 ns • Automatic power-down when deselected • Low active power — 660 mW • Low standby power — 140 mW • CMOS for optimum speed/power • TTL-compatible inputs and outputs • Easy memory expansion with CE1, CE2, and OE features provided by an active-LOW chip enable (CE1), an active-HIGH chip enable (CE2), an active-LOW output enable (OE), and three-state drivers. The device has an automatic power-down feature that reduces power consumption by more than 75% when deselected. Writing to the device is accomplished by taking CE1 and write enable (WE) inputs LOW and CE2 input HIGH. Data on the nine I/O pins (I/Oo – I/O8) is then written into the location specified on the address pins (A0 – A14).
