Frequently Asked Questions
What type of display does the CD4055BE drive?
The CD4055BE is specifically designed to drive liquid crystal displays (LCDs) in 7-segment format, converting 4-bit BCD input data into the appropriate 7-segment output signals to display numeric digits from 0 to 9 on a single LCD digit.
Does the CD4055BE support multiplexed display driving?
No, the CD4055BE does not support multiplexed display operation. It is a single-channel, non-multiplexed LCD driver intended for direct drive of one 7-segment LCD digit, making it simple to use but limited to single-digit display applications.
What package does the CD4055BE use?
The CD4055BE comes in a 16-pin Dual In-Line Package (DIP), with JESD-30 code R-PDIP-T16. This through-hole package is easy to use in prototyping on breadboards and is compatible with standard DIP IC sockets for legacy and educational electronics projects.
What is the data input mode of the CD4055BE?
The CD4055BE uses parallel data input mode, accepting a 4-bit BCD code simultaneously on its input pins. This allows direct connection to the output port of a microcontroller or BCD output device without any serial communication overhead.
