IDT7188L

CMOS STATIC RAM 64K (16K x 4-BIT) Integrated Device Technology, Inc. IDT7188S IDT7188L FEATURES: High-speed (equal access and cycle times) — Military: 25/35/45/55/70/85ns (max.) Low power consumption Battery backup operation — 2V data retention (L version only) Available in high-density industry standard 22-pin, 300 mil ceramic DIP Produced with advanced CMOS technology Inputs/outputs TTL-compatible Military product compliant to MIL-STD-883, Class B DESCRIPTION: The IDT7188 is a 65,536-bit high-speed static RAM organized as 16K x 4. It is fabricated using IDT’s highperformance, high-reliability technology — CMOS. This stateof-the-art technology, combined with innovative circuit design techniques, provides a cost effective approach for memory intensive applications. Access times as fast as 25ns are available. The IDT7188 offers a reduced power standby mode, ISB1, which is activated when CS goes HIGH. This capability significantly decreases power while enhancing system reliability. The low-power version (L) version also offers a battery backup data retention capability where the circuit typically consumes only 30µW operating from a 2V battery. All inputs and outputs are TTL-compatible and operate from a single 5V supply. The IDT7188 is packaged in 22-pin, 300 mil ceramic DIP providing excellent board-level packing densities. Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to milita...
