DESCRIPTION

The HCC4054B, HCC4055B and HCC4056B (ex-
tended temperature range) and the HCF4054B,
HCF4055B and HCF4056B (intermediate tempera­turerange) aremonolithicintegratedcircuitsavailable
in 16-lead dual in-line plastic orceramic package and
plastic micro package. The HCC/HCF4055B and
HCC/HCF4056B typesare single-digit BCD-to-7-seg­ment decoder/driver circuits that provide level-shifting
functions on the chip. This feature permits the BCD
input-signal swings (VDDtoVSS) to be thesame as

ordifferentfromthe7-segmentoutput-signalswings
(VDDto VEE). For example, the BCD input-signal
swings (VDDto VSS) may be as low as 0 to – 3V,
whereasthe output-display drive-signal swing (V
to VEE)maybefrom0to–5V.IfVDDtoVEEexceeds
15V, VDDto VSSshould be at least 4V. The 7-seg­ment outputs are controlled by the DISPLAY-FRE­QUENCY (DF) input which causes the selected
segmentoutputs to below, high, or a square-wave
output (for liquid-crystal displays). When the DF
input is low the output segments will be high when
selected by the BCD inputs. When the DF input is
high,theoutputsegments will belowwhenselected
by the BCD inputs. When a square-wave ispresent
at the DF input, the selected segments will have a
square-wave output thatis 180° out of phase with
the DF input. Those segments which are not se­lected will have a square-wave output that is in
phase with the input. DF square-wave repetition
rates for liquid-crystal displays usually range from
30Hz (well above flicker rate) to 200Hz (well below
the upper limit of the liquid-crystal frequency re­sponse). The HCC/HCF4055B provides a level­shifted high-amplitude DF output which is required
for driving the common electrode in liquid-crystal
displays. The HCC/HCF4056B provides a strobed­latch function at the BCD inputs. Decoding of all
input combinations on the HCC/HCF4055B and
HCC/HCF4056Bprovides displays of 0 to 9as well

vides level shifting similar to the HCC/HCF4055B
andHCC/HCF4056B independently strobedlatches,
and common DF control on 4 signal lines. The
HCC/HCF4054Bisintended toprovide drive-signal
compatibility with the HCC/HCF4055B and
HCC/HCF4056B 7-segment decoder types for the
decimalpoint,colon,polarity,andsimilardisplaylines.
A level-shifted high-amplitude DF output canbe ob­tainedfrom anyHCC/HCF4054B outputlinebycon-
necting the corresponding inputand strobe lines to
a low and high level, respectively. The
HCC/HCF4054Bmayalso be utilizedfor logic-level
”upconversion” or ”downconversion”. Forexample,
input-signal swings (VDDtoVSS) from + 5 to 0V can
be convertedtooutput-signal swings(VDDtoVEE)of
+ 5 to – 5V. The level-shifted function on all three
types permits the use of different input-and output­signal swings. The inputswingsfrom a lowlevelof
VSSto a high level of VDDwhile the output swings

fromalowlevel ofVEEtothesame highlevel ofVDD.
Thus, the inputand output swings can be selected
independently of each otherovera 3-to-18V range.
VSSmay be connected to VEEwhen no level-shift
function is required. For the HCC/HCF 4054B and
HCC/HCF4056B, dataaretransferredfrominput to
output by placing a high voltage level at thestrobe
input. A low voltage levelat the strobe input latches
the data input and the corresponding output seg­ments remain selected (or non-selected) whilethe
strobe is low.Whenever the level-shifting function
is required, the HCC/HCF4055B can be usedby it-
self to drive a liquid-crystal display (fig. 10 and fig.

12). The HCC/HCF4056B, however,must be used
together withaHCC/HCF4054Btoprovide thecom­mon DFoutput (fig. 14).Thecapability of extending
the voltage swing on thenegative end(this voltage
cannot be extended on the positive end) can be
used to advantage in theset-up of fig.11. Fig. 9 is
commonto all three types.
