What are the key features of CD4056BEE4?

3V to 18V wide supply range enables use across battery-powered and mains-derived LCD meter designs
Direct 7-segment LCD segment outputs with on-chip BCD latch remove need for external decoder logic
Non-inverting parallel data input supports direct connection to microcontroller GPIO without logic inversion

What is CD4056BEE4 used for?

CD4056BEE4 is designed for digital panel meters, clock displays, and industrial instrument readouts using static 7-segment LCD panels. Its wide supply range (3V to 18V) makes it compatible with battery-powered portable instruments as well as 12V industrial control panels. The single-digit architecture suits frequency counters, temperature meters, and lab equipment where independent digit control simplifies firmware design.

Frequently Asked Questions

What supply voltage range does CD4056BEE4 support, and how does that affect LCD segment drive voltage?

CD4056BEE4 operates from 3V to 18V. At higher supply voltages such as 12V, segment drive swing is larger, which suits LCD panels requiring 5V to 10V AC drive, while 3.3V or 5V operation suits modern microcontroller-based portable meter designs.

Does CD4056BEE4 support multiplexed LCD drive, or is it limited to static segment drive?

CD4056BEE4 is a non-multiplexed static LCD driver with 7 segment outputs for a single digit. There is no backplane multiplexing support; each of the 7 segments is driven independently, making it ideal for low-power static LCD applications at frequencies from DC to several hundred Hz.

How does the BCD latch in CD4056BEE4 simplify microcontroller interfacing for a 4-digit panel meter?

The on-chip BCD latch in CD4056BEE4 stores the 4-bit parallel input, so the microcontroller only needs to assert the data and strobe lines momentarily rather than holding the bus. This frees up 4 GPIO lines per digit and allows up to 4 CD4056B devices to share a common 4-bit data bus using independent latch-enable signals.

When would CD4056BEE4 in a 16-pin DIP be chosen over a modern LCD controller with I2C interface for a bench instrument?

CD4056BEE4 suits designs where simplicity and availability matter more than feature density: it requires no firmware library, no I2C stack, and operates at 3V to 18V without calibration. For 1- to 4-digit static LCD readouts in industrial environments with 5V or 12V rails, this 16-pin DIP solution has lower latency and no bus contention risk.
