DESCRIPTION:

FEATURES:

The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that

loadandemptydataonafirst-in/first-outbasis.Thesedevicesarefunctional

andcompatibletotwoIDT7200/7201/7202/7203/7204/7205FIFOsinasingle

The IDT7280 is equivalent to two IDT7200 256 x 9 FIFOs

The IDT7281 is equivalent to two IDT7201 512 x 9 FIFOs

The IDT7282 is equivalent to two IDT7202 1,024 x 9 FIFOs

The IDT7283 is equivalent to two IDT7203 2,048 x 9 FIFOs

The IDT7284 is equivalent to two IDT7204 4,096 x 9 FIFOs

The IDT7285 is equivalent to two IDT7205 8,192 x 9 FIFOs

— Active: 685 mW (max.)

— Power-down: 83 mW (max.)

Ultra high speed—12 ns access time

Asynchronous and simultaneous read and write

Offers optimal combination of data capacity, small foot print

and functional flexibility

Ideal for bi-directional, width expansion, depth expansion,

bus-matching, and data sorting applications

Status Flags: Empty, Half-Full, Full

Auto-retransmit capability

High-performance CMOS technology

Space-saving TSSOP

Industrial temperature range (–40°C to +85°C) is available
