2K x 8 Static RAM

Model CD74HC147E

The CY6116A and CY6117A are high-performance CMOS static RAMs organized as 2048 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE), and three-state drivers, The CY6116A and CY6117A have an automatic power-down feature reducing the power consumtion by 83% when deselected.

Writing to the device is accomplished when the chip enable (CE) and write enable (WE) inputs are both LOW. Data on the I/O pins. Data on the I/O pins is written into the memory location specified on the address pins.

Reading the device is accomplished by taking chip enable (CE) and Output Enable (OE) LOW while write enable (WE) remains high. Under these conditions, the contents of the memory location specified on the address pins will appear on the I/O pins.

The I/o pins remain in high impedance state when chip enable (CE) is HIGH or write enable (WE) is LOW.

The CY6116A and CY6117A utilize a die coat to insure alpha immunity.
