It drives a single LCD digit from a 3V to 18V supply, drawing only 40 nA typical — low enough that the display driver's own consumption is negligible in battery-powered instruments. The 40 nA supply current means the driver adds negligible load to the system supply — in a battery-backed data logger, the LCD driver's draw is below the self-discharge rate of the battery itself. The -55°C to 125°C operating range covers military and industrial temperature extremes — the same part works in an outdoor telecom cabinet and an engine-bay instrumentation pod without a grade change. The BCD interface accepts 4-bit binary-coded decimal input and latches it, so the microcontroller writes the digit once and the display holds without refresh overhead — freeing the MCU for other tasks.","metaTitle":"CD4056BPW LCD 7-Segment Driver, 16-TSSOP, 3-18V","metaDescription":"CD4056BPW BCD-to-7-segment LCD driver in 16-TSSOP.
