The configuration supports 7-segment numeric, alphanumeric, and bar-graph segments, so the same part drives a multi-character readout or a simple bargraph panel. ## 44-PLCC package — rework and board-fit The 44-lead PLCC with J-leads (44-LCC J-Lead) is a surface-mount package that hand-solders well with a fine-tip iron — the J-lead wicks solder under the body. ## Serial interface and temperature grade The serial interface is a simple shift-register load — no I²C or SPI protocol overhead, just data, clock, and latch lines that any GPIO bank can bit-bang.","metaTitle":"Texas Instruments MM145453V/NOPB LCD Driver, 4.5-Digit","metaDescription":"Texas Instruments MM145453V/NOPB LCD driver IC, 4.5-digit, 40 µA supply, 3V-10V range, 44-PLCC.
