ordifferent from the7-segment output-signal swings

(V_DDto V_EE). For example, the BCD input-signal

swings (V_DDto V_SS) may be as low as 0 to – 3V,

whereas the output-display drive-signal swing (V_DD

to V_EE) may be from 0 to – 5V. If V_DDtoV_EEexceeds

15V, V_DDto V_SSshould 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 below 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

DESCRIPTION

The HCC4054B, HCC4055B and HCC4056B (ex-

tended temperature range) and the HCF4054B,

HCF4055B and HCF4056B (intermediate tempera-

ture range) are monolithic integrated circuitsavailable

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 (V_DDto V_SS) to be the same as
