DESCRIPTION

The HCC4026B/4033B (extended temperature
range) and HCF4026B/4033B (intermediate tem-
perature range) are monolithic integrated circuits,
available in 16-lead dual in-line plastic or ceramic
package and plastic micro package. The
HCC/HCF4026B and HCC/HCF4033B each con­sist of a 5-stage Johnson decade counter and an
outputdecoder which convertsthe Johnsoncodeto
a 7-segment decoded output for driving one stage
in a numerical display. These devices are particu­larly advantageous in display applications where
lowpower dissipationand/or low packagecount are
important. Inputs common to both types are
CLOCK,RESET,& CLOCKINHIBIT; commonout­puts are CARRYOUT and the seven decoded out­puts(a,b,c,d, e, f,g). Additional inputsandoutputs
fortheHCC/HCF4026B include DISPLAY ENABLE
input and DISPLAY ENABLE and UNGATED ”C­SEGMENT” outputs. Signals peculiar to the
HCC/HCF4033B are RIPPLE-BLANKING INPUT
AND LAMP TEST INPUT and a RIPPLE-BLANK­INGOUTPUT.A high RESET signal clears the de-

cade counter to its zero count. The counter is ad­vanced one count at the positive clock signal tran­sition if the CLOCK INHIBIT signal is low. Counter
advancement viathe clocklineisinhibited whenthe
CLOCK INHIBIT signal is high. Antilock gating is
provided on the JOHNSON counter, thus assuring
propercounting sequence. The CARRY-OUT(C

out

signal completes one cycle every ten CLOCK
INPUT cycles and isused to clockthe succeeding
decade directly in a multi-decade counting chain.
The sevendecoded outputs (a,b, c,d,e, f, g) illumi­nate the proper segments in a sevensegment dis­play device used for representing the decimal
numbers 0 to 9. The 7-segment outputs go high on
selection in the HCC/HCF4033B ; in the HCC/-
HCF4026B these outputs go high only when the
DISPLAY ENABLEIN is high.

HCC/HCF4026B- Whenthe DISPLAYENABLE IN
is lowthe seven decoded outputs are forced low re­gardless of the state of thecounter. Activationof the
display only when required results in significant
power savings. This system also facilitates im­plementation of display-character multiplexing. The
CARRY OUT and UNGATED ”C-SEGMENT” sig­nals are not gated by the DISPLAY ENABLE and
therefore are availablecontinuously. This feature is
a requirement in implementation of certain divider
functionssuch as divide-by-60 and divide-by-12.

HCC/HCF4033B-TheHCC/HCF4033B has provi-
sions for automatic blanking of the non-significant
zeros in amulti-digit decimal numberwhichresults
in an easily readable display consistent with

normal writing practice. For example, the number

0050.07000 in an eight digit display would be dis­played as 50.07. Zero suppression on the integer
side is obtained by connecting the RBI terminal of
the HCC/HCF4033B associated with the most sig­nificantdigit in thedisplay to alow-level voltageand

)

connectingtheRBOterminal ofthatstagetotheRBI
terminal of the HCC/HCF4033B in the next-lower
significant position in the display. This procedure is
continued foreach succeedingHCC/HCF4033Bon
the integer side of thedisplay. On thefractionside
of the display the RBIof the HCC/HCF4033B asso-
ciatedwiththe leastsignificant bitis connected to a
low-level voltage and the RBO of that HCC/-

HCF4033B is connected to the RBI terminal of the
HCC/HCF4033B inthenext more-significant-bit po-

sition. Again, this procedure is continued for all
HCC/HCF4033B’s on the fraction side of the dis­play.In a purely fractionalnumberthezero immedi­ately preceding the decimal point can be displayed
by connecting the RBI of that stageto a high level
voltage(instead of tothe RBO of thenextmore-sig­nificant-stage). For example : optional zero →

0.7346. Likewise, the zero in a number such as

763.0canbedisplayedbyconnecting the RBI ofthe
HCC/HCF4033B associated with it to a high-level
voltage. Ripple blanking of non-significant zeros
provides an appreciable savings in display power.
The HCC/HCF4033B has a LAMP TEST input
which, when connected to a high-level voltage,
overrides normal decoder operation and enables a
checkto be made on possible displaymalfunctions
by putting the sevenoutputsin thehigh state.
