Output Enable (OE) available added system flexibility Low-power consumption JEDEC compatible pinout Battery back-up operation-2V data retention version only) 24-pin CERDIP, high-density 28-pin leadless chip carrier, 24-pin Produced with advanced CMOS technology Bidirectional data inputs outputs Military product compliant MIL-STD-883, Class
DESCRIPTION:
IDT6198 65,536-bit high-speed static organized fabricated using IDT's high-performance, high-reliability technology-CMOS. This state-of-theart technology, combined with innovative circuit design tech-
niques, provides cost-effective approach memory intensive applications. Timing parameters have been specified meet speed demands IDT79R3000 RISC processors. Access times fast 15ns available. IDT6198 offers reduced power standby mode, ISB1, which activated when goes HIGH. This capability significantly decreases system, while enhancing system reliability. low-power version also offers battery backup data retention capability where circuit typically consumes only 30µW when operating from battery. inputs outputs TTL-compatible operate from single supply. IDT6198 packaged either 24-pin CERDIP, 28-pin leadless chip carrier 24-pin J-bend small outline Military grade product manufactured compliance with latest revision MIL-STD-883, Class making ideally suited military temperature applications demanding highest level performance reliability.

NOTES: must HIGH during address transitions. write occurs during overlap tWP) measured from earlier going HIGH write cycle. During this period, pins output state that input signals must applied. transition occurs simultaneously with after transition, outputs remain high-impedance state. Transition measured ±200mV from steady state. during controlled write cycle, write pulse width must larger (tWHZ tDW) allow drivers turn data placed required tDW. HIGH during controlled write cycle, this requirement does apply write pulse short specified tWP.
