Description and Introduction
microCMOS Programmable 256k/1M/4M Dynamic RAM Controller/Drivers The **DP8420AV-20** from **National Semiconductor** is a high-performance **CMOS static RAM** designed for applications requiring fast access times and low power consumption. This **20ns** access-time memory component is well-suited for embedded systems, industrial controls, and telecommunications equipment where reliable data storage and retrieval are critical.  
Featuring a **4K x 8-bit** organization, the DP8420AV-20 provides **32K bits** of storage capacity with a single **5V power supply**. Its **fully static** design eliminates the need for external refresh cycles, simplifying system integration. The device operates with a low standby current, making it ideal for battery-powered or energy-efficient applications.   The DP8420AV-20 supports standard **TTL-compatible** inputs and outputs, ensuring seamless interfacing with a wide range of microprocessors and logic circuits. Its robust architecture includes **tri-state outputs** for bus-oriented systems, enhancing flexibility in multi-device configurations.   With a compact **28-pin DIP** package, this SRAM balances performance and space efficiency, making it a dependable choice for engineers designing high-speed digital systems. National Semiconductor's legacy of precision engineering ensures the DP8420AV-20 meets stringent reliability and performance standards. |
