Product details

Supply voltage and current — what they mean for your BOM

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.

Lifecycle and sourcing posture

The CD4055BPW is listed as Active and ROHS3 compliant. For volume production or BOM freeze, we can quote firm pricing and lead time on request.

Frequently asked questions

How many digits can CD4055BPW drive?

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.

Is CD4055BPW a direct replacement for CD4055BE?

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.
