•

Ultra high speed—12ns access time

Asynchronous and simultaneous read and write

Fully expandable by both word depth and/or bit width

Pin and functionally compatible with 720X family

Status Flags: Empty, Half-Full, Full

Auto-retransmit capability

High-performance CEMOS™ technology

Military product compliant to MIL-STD-883, Class B

Standard Military Drawing #5962-87531, 5962-89666, 5962-89863

and 5962-89536 are listed on this function

Dual versions available in the TSSOP package. For more informa-

tion, see IDT7280/7281/7282 data sheet

IDT7280 = 2 x IDT7200

The reads and writes are internally sequential through the use of ring

pointers,withnoaddressinformationrequiredtoloadandunloaddata. Data
