The 3V to 18V supply range is the first thing to check against your existing rail. If your board already carries a 5V or 12V supply, this part drops in without a secondary regulator. The 40 nA supply current is essentially negligible for battery-powered or always-on designs.

It drives one digit of a 7-segment LCD display. For multi-digit displays, you need one CD4055BPW per digit or a multiplexed driver IC.
The CD4055BPW is the surface-mount TSSOP version of the same CD4055 function. The CD4055BE is the through-hole DIP variant. Electrically they are identical — same BCD-to-7-segment LCD driver, same supply range, same temperature grade. The only difference is the package and mounting method.
