Static
High speed CMOS optimum speed/power active power standby power 2.0V data retention (optional) Automatic power-down when deselected TTL-compatible inputs outputs memory expansion provided active Chip Enable (CE) three-state drivers. These devices have automatic power-down feature that reduces power consumption more than when deselected. Writing devices accomplished taking Chip Enable (CE) Write Enable (WE) inputs LOW. Data input (DIN) written into memory location specified address pins through A19). Reading from devices accomplished taking Chip Enable (CE) while Write Enable (WE) remains HIGH. Under these conditions, contents memory location specified address pins will appear data output (DOUT) pin. output (DOUT) placed high-impedance state when device deselected HIGH) during write operation LOW). CY7C107 available standard 400-mil-wide SOJ; CY7C1007 available standard 300-mil-wide SOJ.
