• 720x family is pin and functionally compatible from 256 x 9 to 64k x 9

• 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
