DESCRIPTION
The HCC4054B, HCC4055B and HCC4056B (ex-
tended temperature range) and the HCF4054B,
HCF4055B and HCF4056B (intermediate tempera-
ture range) are monolithic integrated circuits available
in 16-lead dual in-line plastic or ceramic package and
plastic micro package. The HCC/HCF4055B and
HCC/HCF4056B types are 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 (VDD to VSS) to be the same as

or different from the 7-segment output-signal swings
(VDD to VEE). For example, the BCD input-signal
swings (VDD to VSS) may be as low as 0 to – 3V,
whereas the output-display drive-signal swing (VDD
to VEE) may be from 0 to – 5V. If VDD to VEE exceeds
15V, VDD to VSS should be at least 4V. The 7-seg-
ment outputs are controlled by the DISPLAY-FRE-
QUENCY (DF) input which causes the selected
segment outputs to be low, 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, the output segments will be low when 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 phase with
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

as L, P, H, A,– , and a blank position. (see typical ap-
plication for other letters). The HCC/HCF4054B pro-
vides level shifting similar to the HCC/HCF4055B
and HCC/HCF4056B independently strobed latches,
and common DF control on 4 signal lines. The
HCC/HCF4054B is intended to provide drive-signal
compatibility with the HCC/HCF4055B and
HCC/HCF4056B 7-segment decoder types for the
decimal point, colon, polarity, and similar display lines.
A level-shifted high-amplitude DF output can be ob-
tained from any HCC/HCF4054B output line by con-
necting the corresponding input and strobe lines to
a low and high level, respectively. The
HCC/HCF4054B may also be utilized for logic-level
”up conversion” or ”down conversion”. Forexample,
input-signal swings (VDD to VSS) from + 5 to 0V can
be converted to output-signal swings (VDD to VEE) of
+ 5 to – 5V. The level-shifted function on all three
types permits the use of different input-and output-
signal swings. The input swings from a low level of
VSS to a high level of VDD while the output swings

from a low level of VEE to the same high level of VDD.
Thus, the input and output swings can be selected
independently of each other over a 3-to-18V range.
VSS may be connected to VEE when no level-shift
function is required. For the HCC/HCF 4054B and
HCC/HCF 4056B, data are transferred from input to
output by placing a high voltage level at the strobe
input. A low voltage level at the strobe input latches
the data input and the corresponding output seg-
ments remain selected (or non-selected) while the
strobe is low. Whenever the level-shifting function
is required, the HCC/HCF4055B can be used by it-
self to drive a liquid-crystal display (fig. 10 and fig.
12). The HCC/HCF4056B, however, must be used
together with a HCC/HCF4054B to provide the com-
mon DF output (fig. 14). The capability of extending
the voltage swing on the negative end (this voltage
cannot be extended on the positive end) can be
used to advantage in the set-up of fig. 11. Fig. 9 is
common to all three types.
