• Partial Reset clears data, but retains programmable settings

• Empty, Full and Half-Full flags signal FIFO status

• Programmable Almost-Empty and Almost-Full flags, each flag can

default to one of eight preselected offsets

• Selectable synchronous/asynchronous timing modes for Almost-

Empty and Almost-Full flags

• Program programmable flags by either serial or parallel means

• Select IDT Standard timing (using EF and FF flags) or First Word

Fall Through timing (using OR and IR flags)

• Output enable puts data outputs into high impedance state

• Easily expandable in depth and width
