256-word X 4-bit Lsi Static Ram

The CDP1822 and CDP1822C are 256-word by 4-bit static random-access Memories designed for use in memory sys- tems where high speed, low operating current, and simplicity in use are desirable. The CDP1822 features high speed and a wide operating voltage range. Both types have separate data inputs and outputs and utilize single power supplies of 4V to 6.5V for the CDP1822C and 4V to 10.5V for the CDP1822. Two Chip-Select inputs are provided to simplify system expansion. An Output Disable control provides Wire-OR capability and is also useful in common Input/Output sys- tems. The Output Disable input allows these RAMs to be used in common data Input/Output systems by forcing the output into a high-impedance state during a write operation independent of the Chip-Select input condition. The output assumes a high-impedance state when the Output Disable is at high level or when the chip is deselected by CS1 and/or CS2. By Intersil Corporation
