DESCRIPTION
TheHCC40105B (extended temperature range) and
HCF40105B (intermediate temperature range) are
monolithicintegratedcircuits,available in16-leaddual
in-line plastic orceramic package.
TheHCC/HCF40105B is alow-power first-in-first-out
(FIFO)”elastic”storageregisterthatcanstore164-bit
words. It iscapable ofhandling input and output data
atdifferent shiftingrates.Thisfeaturemakesitparticularly useful as a buffer between asynchronous systems.Eachword position in the register is clocked by
a controlflip-flop, which stores a markerbit.A”1”signifiesthattheposition’sdata is filledanda”0” denotes
a vacancy inthatposition. Thecontrolflip-flopdetects
the state of the preceding flip-flop and communicates
itsownstatus tothesucceeding flip-flop.When acontrol flip-flop is in the ”0” state and sees a ”1” in the
preceding flip-flop, it generates a clock pulse that
transfers data from the preceding four data latches
intoitsownfourdata latches andresetsthepreceding
flip-flopto ”0”. The first and lastcontrolflip-flops have
buffered outputs. Since all empty locations ”bubble”
automatically tothe input end, and allvaliddataripple
throughtotheoutput end,thestatusof thefirstcontrol
flip-flop(DATA-IN READY)indicatesiftheFIFOisfull,
and the status of the last flip-flop (DATA-OUT
READY) indicates if the FIFO contains data. As the
earliest data areremoved from thebottomofthe data
stack(theoutputend), alldata entered later willautomaticallypropagate (ripple) toward the output.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
