The MC14543B BCD–to–seven segment latch/decoder/driver is
designed for use with liquid crystal readouts, and is constructed with
complementary MOS (CMOS) enhancement mode devices. The
circuit provides the functions of a 4–bit storage latch and an 8421
BCD–to–seven segment decoder and driver. The device has the
capability to invert the logic levels of the output combination. The
phase (Ph), blanking (BI), and latch disable (LD) inputs are used to
reverse the truth table phase, blank the display, and store a BCD code,
respectively. For liquid crystal (LC) readouts, a square wave is applied
to the Ph input of the circuit and the electrically common backplane of
the display. The outputs of the circuit are connected directly to the
segments of the LC readout. For other types of readouts, such as
light–emitting diode (LED), incandescent, gas discharge, and
fluorescent readouts, connection diagrams are given on this data sheet.
Applications include instrument (e.g., counter, DVM etc.) display
driver, computer/calculator display driver, cockpit display driver, and
various clock, watch, and timer uses.

This device contains protection circuitry to guard
against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid ap-
plications of any voltage higher than maximum rated
voltages to this high–impedance circuit. For proper
operation, V
in
and V
out
should be constrained to the
range V
SS
(V
in
or V

)
Unused inputs must always be tied to an appropriate
logic voltage level (e.g., either V
SS
or V
DD
). Unused out-
puts must be left open.
