Description
The CDP1822 and CDP1822C are 256-word by 4-bit static random-access memories designed for use in memory systems where high speed, low operating current, and simplicity in use are desirable.
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 systems. The Output Disable input allows these RAMs to be used in common data Input/Output systems by forcing the output into a high-impedance s.
