General Description
The MM5452isa monolithic integrated circuit utilizing
CMOS metal gate,low threshold enhancement mode devic-
es.Itis availableina 40-pin molded package.The chipcan
driveupto32 segmentsof LCDand canbe paralleledto
increasethis number. The chipis capableof drivinga4(/2-
digit 7-segment display with minimal interface betweenthe
displayandthe data source.
The MM5452 stores display datain latches afteritis
clockedin,and holdsthe data until new display dataisre-
ceived.
Features Serial data inputNo load signal required DATA ENABLE (MM5452) Wide power supply operation TTL compatibility32or33 outputs Alphanumericandbar graph capability Cascaded operation capability
Applications COPSTMor microprocessor displays Industrial control indicator Digital clock, thermometer, counter, voltmeter Instrumentation readouts Remote displays
