General description
The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED
displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an
active HIGH blanking input (BL), an active HIGH phase input (PH) and seven buffered
segment outputs (Qa to Qg).
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 (BL) and latch enable (LE) 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.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V

also suitable for use over the full industrial (
