BCD to 7-segment latch/decoder/driver
HEF4543B

DESCRIPTION
The HEF4543B is a BCD to 7-segment
latch/decoder/driver for liquid crystal and LED displays. It
has four address inputs (D
A
to D
D
), an active HIGH latch
disable input (LD), an active HIGH blanking input (BI), an
active HIGH phase input (PH) and seven buffered
segment outputs (O
a
to O
g
).
The circuit provides the function of a 4-bit storage latch
and an 8-4-2-1 BCD to 7-segment decoder/driver. It can
invert the logic levels of the output combination. The phase
(PH), blanking (BI) and latch disable (LD) inputs are used
to reverse the function table phase, blank the display and
store a BCD code, respectively.
For liquid crystal displays a square-wave is applied to PH
and the electrical common back-plane of the display. The
outputs of the device are directly connected to the
segments of the liquid crystal.
