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
