DP8419N-80** is a DRAM (Dynamic Random-Access Memory) chip manufactured by **National Semiconductor (NS)**.

The DP8419N-80 is a DRAM (Dynamic Random-Access Memory) chip manufactured by National Semiconductor (NS). Below are the key specifications, descriptions, and features:

Specifications:

  • Part Number: DP8419N-80
  • Manufacturer: National Semiconductor (NS)
  • Type: DRAM (Dynamic RAM)
  • Density: 64K x 1 (65,536 bits)
  • Speed: 80 ns (nanoseconds) access time
  • Voltage Supply: +5V
  • Package: 16-pin DIP (Dual In-line Package)
  • Operating Temperature Range: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant

Descriptions:

  • The DP8419N-80 is a high-speed, low-power 64K x 1 DRAM chip designed for use in memory expansion applications.
  • It features a multiplexed address bus (A0-A7) to reduce pin count.
  • Requires periodic refresh cycles to maintain data integrity.

Features:

  • 64K x 1 Organization – Stores 65,536 bits in a single chip.
  • Fast Access Time – 80 ns access speed for efficient performance.
  • Low Power Consumption – Optimized for power-sensitive applications.
  • Single +5V Supply – Compatible with standard TTL logic levels.
  • Multiplexed Addressing – Uses row and column address strobes (RAS, CAS) for efficient memory access.
  • 16-Pin DIP Package – Standard through-hole mounting for easy integration.

This chip was commonly used in early computer systems, industrial controls, and embedded applications requiring DRAM memory expansion.
