The standout feature is the 40 nA typical supply current — that is essentially leakage-level draw, so it works in battery-powered or always-on designs where every microamp matters.
This variant comes in a 16-SOIC package (0.154" body width, 3.90 mm) for surface-mount assembly. The supplier device package is 16-SOIC.
Electrically yes — same BCD-to-7-segment LCD driver function, same supply range, same temperature grade. The difference is the package: CD4056BE is a DIP, while CD4056BM96 is a surface-mount SOIC-16. The PCB footprint is different, so it is not a direct physical swap on an existing DIP board.
It drives a single digit (1 digit) in a 7-segment LCD configuration. For multi-digit displays you would need one driver per digit or a multiplexed controller.
The evidence does not list a current limiting feature. The part is a voltage-mode LCD segment driver — the segment drive is a switched voltage, not a regulated current. For segment current limiting you would typically add external resistors or use a different driver type.
