Features Serial data input No load signal required ^DATA ENABLE (MM5452) Wide power supply operation TTL compatibility 32 or 33 outputs Alphanumeric and bar graph capability Cascaded operation capability Description The MM5452 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 32 segments of LCD and can be paralleled to increase this number. The chip is capable of driving a 4½-digit 7-segment display with minimal interface between the display and the data source. The MM5452 stores display data in latches after it is clocked in, and holds the data until new display data 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)
MM5452N	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.
