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 (V

to V

) to be the same as

March 1989

or different from the 7-segment output-signal swings

to V

). For example, the BCD input-signal

swings (V

to V

) may be as low as 0 to 鈥?3V,

whereas the output-display drive-signal swing (V

to V

) may be from 0 to 鈥?5V. If V

to V

exceeds

15V, V

to V

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擄 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
