This device features advanced circuit design to provide ultra low standby current. This is ideal for providing More Battery Life™ (MoBL) in portable 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/O0 through 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). To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A18). 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. For a complete list of related documentation, click here.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3 V, and output loading of the specified IOL/IOH as shown in the Figure 2 on page 5. 16. At any temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any device. 17. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state. 18. The internal wre.ite time of the memory is defined by the overlap of WE, CE = VIL. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing should be referenced to the edge of the signal that terminates the write. 19. The minimum write cycle pulse width for Write Cycle No. 3 (WE controlled, OE LOW) should be equal to the sum of tSD and tHZWE.
