HCF4056B
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 selected 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 response). HCF4056B
provides a strobed-latch function at the BCD
inputs. The decoding of all input combinations in

this device provides displays of 0 to 9 as well as L,
P, H, A, -, and a blank position. The level shifted
function permits the use of different input and
output signal swings. The input swings from a low
level of V
outputs swing from a low level of V
high level of V
swings can be selected independently of each
other over a 3 to 18V range. V

together with HCF4054B to provide the common
DF output.
