DESCRIPTION
The M54/74HC4543 is a high speed CMOS BCD-
TO-7 SEGMENT DECODER WITH LCD DRIVER
fabricated in silicon gate C
speed latch and decode operation 120 times as fast
as standard CMOS 4511B while CMOS low power
consumption in maintained. This device consist 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 dis-
play. For other types of readouts, such as light-emit-
ting 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.
