MILITARY TEMPERATURE RANGE MAY 1994 ©1994 Integrated Device Technology, Inc. 6.4 DSC-1027/4 ® CMOS STATIC RAMs 64K (16K x 4-BIT) Added Chip Select and Output Controls IDT7198S IDT7198L FEATURES: • Fast Output Enable ( OE) pin available for added system flexibility • Multiple Chip Selects ( CS1, CS2) simplify system design and operation • High speed (equal access and cycle times) — Military: 20/25/35/45/55/70/85ns (max.) • Low power consumption • Battery back-up operation—2V data retention (L version only) • 24-pin CERDIP, high-density 28-pin leadless chip carrier, and 24-pin CERPACK packaging available • Produced with advanced CMOS technology • Bidirectional data inputs and outputs • Inputs/outputs TTL-compatible • Military product compliant to MIL-STD-883, Class B DESCRIPTION: The IDT7198 is a 65,536 bit high-speed static RAM orga- nized as 16K x 4. It is fabricated using IDT’s high-perfor- mance, high-reliability technology—CMOS. This state-of-the- art technology, combined with innovative circuit design tech- niques, provides a cost effective approach for memory inten- sive applications. Access times as fast as 20ns are available. The IDT7198 offers a reduced power standby mode, ISB1, which is activated when CS1 or CS2 goes HIGH. This capability decreases power, while enhancing system reliability. The low-power version (L) also offers a battery backup data retention capa- bility where the circuit typically consumes only 30 µW when operating from a 2V battery. All inputs and outputs are TTL-compatible and operate from a single 5V supply. The lDT7198 is packaged in either a 24-pin ceramic DlP, 28-pin leadless chip carrier, and 24-pin CERPACK. Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
