CMOS BCD to 7Segment Latch/Decoder/Driver for Liquid Crystal Displays
DESCRIPTION
The CD4543B is a BCD to 7-segment latch/decoder/driver
The CD4543B is a BCD to 7-segment latch/decoder/driver
for liquid crystal and LED displays. It has four address inputs
(DA to DD), an active HIGH latch disable input (LD), an active
HIGH blanking input (BI), an active HIGH phase input (PH) and
seven buffered segment outputs (Oa to Og).
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.
