DESCRIPTIONThe M74HC4543 is an high speed CMOS
BCD-TO-7 SEGMENT DECODER WITH LCD
DRIVER fabricated with silicon gate C2 MOS
technology.
This device consists of BCD-TO-7 segment
decoder with a BCD input latch and a 7-segment
driver for a liquid crystal display (LCD). When any
illegal BCD input signal is applied or input BI is
held high, the display is blanked. When driving
LCDs, a common square wave signal should be
applied not only to the PH input of this device but
also to the electrically common backplane of the
display. For other types of readouts, such as
light-emitting diode (LED), some additional
drivers, such as a transistor array is required. All
inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

AC ELECTRICAL CHARACTERISTICS (CL = 50 pF, Input tr = tf = 6ns)
CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/2 (per
FLIP/FLOP)

TEST CIRCUIT CL = 50pF or equivalent (includes jig and probe capacitance)
RT = ZOUT of pulse generator (typically 50Ω)
