UM2149
Overview
The UMC UM2149 is a 4096-8it Static Random Access Memory organized 1024 words by 4 bits and is fabricated using UMC's new N-channel Silicon-Gate HMOS technology. It is designed using fully static circuitry, therefore requiring no clock or refreshing to operate.
- 45 ns maximum address access
- Fully static operation: No clocks or strobes required
- Fast chip select access time: 20ns max.
- Identical cycle and access times
- Single +5V supply
- Industry standard 2114 pinout
- Totally TTL compatible: All inputs and outputs
- Common data input and outputs Ii High density 18-pin package
- Three-state output
