DESCRIPTION:

The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that load and empty data on a first-in/first-out basis. These devices are functional and compatible to two IDT7200/7201/7202/7203/7204/7205 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins. The devices use Full and Empty flags to prevent data overflow and underflow and expansion logic to allow for unlimited expansion capability in both word size and depth.

FEATURES:

• 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
