applications. The device also has an automatic power-down

feature that significantly reduces power consumption when

addresses are not toggling. Placing the device in standby mode

reduces power consumption by more than 99% when deselected

(CE HIGH). The eight input and output pins (I/O₀through I/O₇)

are placed in a high-impedance state when the device is

deselected (CE HIGH), Outputs are disabled (OE HIGH), or

during an active Write operation (CE LOW and WE LOW).

Features

■ Very high speed: 45 ns

■ Wide voltage range: 2.2 V to 3.6 V, 4.5 V to 5.5 V

■ Ultra low standby power

❐ Typical standby current: 3.5 µA

❐ Maximum standby current: 8.7 µA

■ Easy memory expansion with CE and OE features

■ Automatic power-down when deselected

To write to the device, take Chip Enable (CE) and Write Enable

(WE) inputs LOW. Data on the eight I/O pins (I/O₀through I/O₇)

is then written into the location specified on the address pins (A₀

through A₁₈).

■ Complementary metal oxide semiconductor (CMOS) for

optimum speed and power

To read from the device, take Chip Enable (CE) and Output

Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under

these conditions, the contents of the memory location specified

by the address pins appear on the I/O pins.

■ Available in Pb-free 32-pin thin small outline package (TSOP) II

and 32-pin small-outline integrated circuit (SOIC) packages
