The operating temperature range of -40°C to 85°C covers industrial and outdoor equipment, from motor-drive front panels to telecom shelf indicators. ## Key ratings and what they mean for your BOM The 3V to 10V supply range is the headline decision point. At 3.3V nominal the part is fully operational, but check the LCD contrast voltage — the driver's output swing tracks VDD, so a 3.3V rail yields a 3.3V segment drive. If your display needs a higher contrast voltage (common in larger or high-temperature LCDs), you may need to run the driver from a boosted supply within the 10V ceiling. Industrial temperature rating (-40°C to 85°C) means the part is specified for outdoor, unheated, or engine-adjacent enclosures. No derating needed for cold-start or hot-day operation within that range. ## Lifecycle and sourcing reality This is a mature, stable part — no LTB risk for new designs or ongoing production. Note that the part is RoHS non-compliant, so it is not suitable for new European-market consumer products or any assembly requiring RoHS exemption-free status. For repair or legacy builds where leaded solder is acceptable, this is not a blocker.","metaTitle":"National Semiconductor MM5452V LCD Driver, 4.5 Digits","metaDescription":"National Semiconductor MM5452V COPS™ LCD driver: 3V-10V supply, 32-segment, 4.5 digits, -40°C to 85°C, 44-PLCC.

The LCD segment drive voltage will equal the supply, so contrast may be lower than with a 5V rail."},{"question":"What microcontroller interfaces with MM5452V?","answer":"The MM5452V uses a serial data interface, so any microcontroller with a spare serial output (GPIO bit-banged or SPI) can drive it.

The MM5452N is the through-hole DIP version.
