What are the key features of CD4056BE?

Integrated BCD-to-7-segment decoding and LCD drive in a single 16-pin DIP package simplifies display circuit design
Strobed latch function captures and holds BCD input data, reducing the need for external latching logic
Direct LCD drive with non-multiplexed segment outputs for reliable low-power display operation

What is CD4056BE used for?

The CD4056BE is used in digital display systems where a microcontroller or BCD counter output must directly drive a single-digit 7-segment LCD. It is commonly found in handheld meters, digital clocks, industrial panel displays, and consumer appliances requiring a simple numeric readout. The built-in latch allows the display to hold the last valid digit during input changes, which is useful in multiplexed scanning or data-update sequences.

Frequently Asked Questions

What does the CD4056BE do and what type of display does it drive?

The CD4056BE is a CMOS BCD-to-7-segment decoder and driver that converts a 4-bit binary-coded decimal (BCD) input into the 7 segment control signals needed to display digits 0 through 9 on a single-digit LCD. It drives the LCD segments directly without requiring external current-limiting resistors or segment drivers.

What is the strobed latch function in the CD4056BE?

The strobed latch function in the CD4056BE allows the 4-bit BCD input data to be captured and stored internally when a strobe signal is applied. Once latched, the display continues to show the stored digit even if the BCD inputs change. This feature is useful in applications where the input data is only valid for a brief period, such as BCD counters or time-multiplexed data buses.

Can the CD4056BE drive multiple LCD digits?

No, the CD4056BE drives a single digit of a 7-segment LCD display and does not support multiplexed display operation. Its non-multiplexed output directly drives the 7 segments (a through g) of one LCD digit. For multi-digit displays, multiple CD4056BE devices would be required, one per digit, with appropriate backplane drive circuitry.

What package does the CD4056BE use and what is its pin count?

The CD4056BE comes in a 16-pin Dual-In-Line Package (PDIP), identified by JESD-30 code R-PDIP-T16. This through-hole package is compatible with standard 0.1-inch pitch breadboards and socket headers, making it convenient for prototyping and educational circuit designs. It is RoHS compliant as indicated by the JESD-609 code e4.
