LIQUID-CRYSTAL DISPLAY DRIVERS
DESCRIPTION
The
HCC4054B
,
HCC4055B
and
HCC4056B
(ex-
tended temperature range) and the
HCF4054B,
HCF4055B
and
HCF4056B
(intermediate tempera-
turerange) aremonolithicintegratedcircuitsavailable
in 16-lead dual in-line plastic or ceramic package and
plastic micro package. The
HCC/HCF4055B
and
HCC/HCF4056B
typesare single-digit BCD-to-7-seg-
ment decoder/driver circuits that provide level-shifting
functions on the chip. This feature permits the BCD
input-signal swings (V
DD
toV
SS
) to be thesame as

ordifferent fromthe7-segmentoutput-signalswings
(V
DD
to V
EE
). For example, the BCD input-signal
swings (V
DD
to V
SS
) may be as low as 0 to – 3V,
whereasthe output-display drive-signal swing (V
DD
to V
EE
) may befrom0to– 5V.If V
DD
toV
EE
exceeds
15V, V
DD
to V
SS
should be at least 4V. The 7-seg-
ment outputs are controlled by the DISPLAY-FRE-
QUENCY (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 highwhen
selected by the BCD inputs. When the DF input is
high, the output segments will belowwhen selected
by the BCD inputs. When a square-wave is present
at the DF input, the selected segments will have a
square-wave output that is 180
°
out of phasewith
the DF input. Those segments which are not se-
lected 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 re-
sponse). The
HCC/HCF4055B
provides a level-
shifted high-amplitude DF output which is required
for driving the common electrode in liquid-crystal
displays. The
HCC/HCF4056B
provides a strobed-
latch function at the BCD inputs. Decoding of all
input combinations on the
HCC/HCF4055B
and
HCC/HCF4056B
provides displays of 0 to 9 as well
