Features Serial data input Serial data output Wide power supply operation TTL compatibility 31 segment outputs Alphanumeric and bar graph capability Cascade capability Description The MM5483 is a monolithic integrated circuit utilizing CMOS metal-gate low-threshold enhancement mode devices. It is available in a 40-pin molded package. The chip can drive up to 31 segments of LCD and can be cascaded to increase this number. This chip is capable of driving a 4½-digit 7-segment display with minimal interface between the display and the data source. The MM5483 stores the display data in latches after it is latched in, and holds the data until another load pulse is received. Applications COPS ™ or microprocessor displays Industrial control indicator Digital clock, thermometer, counter, voltmeter Instrumentation readouts Remote displays

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
MM5483N	CMOS	0	20300	0	0	2785000	2	790251354
MM5483V	CMOS	0	20300	0	0	2785000	2	790251354

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
