Features Serial Data Input Wide Power Supply operation TTL Compatibility Up to 33 LCD Segments Alphanumeric or Bar Graph capability Cascaded operation capability Pin Compatible with MC145453 Description The MM145453 is a monolithic integrated circuit utilizing CMOS metal gate, low threshold enhancement mode devices. The chip can drive up to 33 LCD segments 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 MM145453 stores display data in latches after it is clocked in, and holds the data until new display data is received. The MM145453 is available in a molded 44 pin surface mount PLCC package. The MM145453 is pin out and functionally compatible with the MC145453. Applications COPS™ or microprocessor displays Industrial control indicator Digital clock, thermometer, counter, voltmeter Instrumentation displays Remote displays

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
MM145453V	CMOS	0	20300	0	0	2785000	2	790251354
MM145453VX	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.
