DESCRIPTION

The M54/74HC192/193 are ahigh speed CMOSSYN­CHRONOUS UP/DOWNDECADE COUNTERS fab­ricatedinsilicon gate C2MOStechnology. They have
thesamehigh speedperformance ofLSTTLcombined
with true CMOS low power consumption. The counter
has two separate clock inputs, an UP COUNT input
and a DOWN COUNT input. All outputs of the flip-flop
are simultaneously triggered on the low to high transi­tionof either clock while theother inputisheldh igh. The
direction of counting is determined by which input is
clocked. This counter may be preset by entering the
desired dataon the DATAA, DATAB, DATA C, and
DATA D input.Whenthe LOADinput istaken lowthe
data is loaded independently of either clock input. This
featureallows the counters to be used asdivide-by-n
counters by modifying the count length with the preset
inputs. Inaddition thecountercanalso becleared. This
is accomplished by inputting a high on the CLEAR
input. All 4 in ternal stages are set to lowindependently
of ei ther COUNTinput. BothaB ORROWa ndCARRY
output areprovided toenablecascadingofbothupand
down counting functions. The BORROWoutput pro­ducesa negativegoingpulsewhen thecounterunder­flows and the CARRY outputs a pulse when the
counter overflows. The counter can be cascaded by
connecting the CARRY and BORROW outputs of one
device to the COUNT UP and COUNTDOWN inputs,
respectively, of thenext device. Allinputs areequipped
with protection circuits against static discharge and
transient excess voltage.
