® CMOS STATIC RAMs 64K (16K x 4-BIT) Added Chip Select and Output Controls IDT7198S IDT7198L Integrated Device Technology, Inc. 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-performance, high-reliability technology—CMOS. This state-of-theart technology, combined with innovative circuit design techniques, provides a cost effective approach for memory intensive 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 capability where the circuit typically consumes only 30µW when operating from a 2V battery. All inputs and outputs are TTL-compatible and operate from a single 5V supply....
