Frequently Asked Questions
What display type is the CD4056BMG4 designed for?
The CD4056BMG4 is specifically designed to drive non-multiplexed liquid crystal display (LCD) segments. It decodes 4-bit BCD input into seven segment drive signals suitable for a single LCD digit, operating without the alternating drive waveform needed for multiplexed displays.
What is the input interface of the CD4056BMG4?
The CD4056BMG4 accepts a 4-bit parallel BCD (Binary Coded Decimal) input representing digits 0 through 9, along with a latch enable input that allows the displayed digit to be held stable while the BCD inputs change, useful for flickering-free display updates.
What supply voltage does the CD4056BMG4 operate on?
The CD4056BMG4 operates from 3 V to 15 V supply, covering 3.3 V microcontroller I/O levels, 5 V logic systems, and 9 V to 12 V power rails commonly used in panel meters and instrumentation, making it highly versatile across different design platforms.
Is the CD4056BMG4 RoHS compliant?
Yes, the CD4056BMG4 is REACH and RoHS compliant, as indicated by its compliance codes. The MG4 suffix variant is RoHS-compliant with lead-free terminals, qualifying it for use in environmentally regulated consumer and industrial electronic products.
