TMS4464-12NL DRAM 64K x 4-bit 120ns IC DIP-18

Description

TMS4464-12NL DRAM 64K x 4-bit 120ns IC DIP-18 The TMS4464-12NL DRAM 64K x 4-bit 120ns IC DIP-18 is a high-performance dynamic random access memory (DRAM) integrated circuit designed and manufactured by Texas Instruments. This device provides 64K words of memory with a 4-bit data width, optimized for page mode operation to enhance access efficiency. The TMS4464-12NL is built using NMOS technology and is housed in an 18-pin dual inline package suitable for through-hole PCB mounting. Its asynchronous access with a maximum access time of 120ns and common 3-STATE outputs make it compatible with a wide range of legacy microprocessor and digital system designs. Features: High-performance 64K × 4-bit dynamic RAM with page mode architecture. Maximum access time of 120ns for fast data retrieval. 3-STATE outputs support bus sharing and bus-driven applications. Operates from a single +5 VDC power supply range (4.5 V–5.5 V). TTL compatible inputs and outputs simplify interfacing with standard logic families. NMOS technology for stable and reliable dynamic memory performance.
