Its supply range of 3V to 10V covers 5V logic rails comfortably, so a 5V microcontroller can drive the serial interface directly without level shifting — the logic input thresholds track the supply, and at Vdd = 5V the part accepts standard 5V CMOS/TTL levels. The wide supply tolerance also suits battery-powered instruments where the rail droops from 6V down to 3V over discharge. ## 44-PLCC (J-Lead) — footprint and thermal reality The part comes in a 44-lead PLCC with J-leads, body size 16.58 mm × 16.58 mm per the supplier device package. Surface-mount assembly is standard, but the J-lead form factor means the solder joint is under the package body — inspect with an angled scope or X-ray after reflow. No exposed pad, so thermal dissipation relies on the leads and board copper; for continuous operation near the 85°C end of the -40°C to 85°C range, ensure adequate copper pour on the PLCC footprint's thermal land. ## Active production, no end-of-life concern The MM5453V/NOPB carries an Active product status and is ROHS3 compliant.","metaTitle":"MM5453V/NOPB LCD Driver IC, 3V-10V Supply, 44-PLCC","metaDescription":"MM5453V/NOPB LCD driver from the COPS™ series.
