CD4056BE

Display Drivers Overview

The CD4056BE is a CMOS LCD driver manufactured by Texas Instruments, designed for driving one digit of a seven-segment display. It operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 8 MHz. The device features a BCD-to-7-segment decoding function with an active-low output configuration suitable for common-anode displays. It is housed in a standard 16-pin PDIP package and is rated for operation across an extended temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Integrates binary-coded decimal (BCD) input logic with internal decoding circuitry to drive seven-segment displays directly.
• Provides active-low outputs specifically configured for compatibility with common-anode liquid crystal display segments.
• Operates reliably across a wide industrial temperature range and supports high-speed clocking up to the specified maximum frequency.

Display Drivers Applications

• Driving single-digit seven-segment LCD indicators in consumer electronics
• Numeric display modules in industrial control panels
• Battery-powered devices requiring low-power LCD readouts

Display Drivers Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the component meets all required electrical specifications for your application, particularly regarding voltage limits and thermal ratings. Check current availability status as inventory levels may vary among authorized distributors.

Display Drivers Selection Notes

Select this component when a dedicated decoder-driver solution is preferred over microcontroller-based implementations for simple numeric displays. Ensure the target display utilizes a common-anode configuration to match the active-low output characteristics. Verify that the system power supply remains within the 3 V to 18 V operational window to guarantee correct signal integrity.

Display Drivers Part Context

This component belongs to the CD4056B series of LCD drivers produced by Texas Instruments. It is part of the broader 4000-series CMOS logic family, known for high noise immunity and low power consumption. The device serves as a specialized interface between digital logic circuits and visual display elements, simplifying the design of numeric readout systems.

Display Drivers Replacement Considerations

Consult official cross-reference data for compatible alternatives such as the CD4056BP or equivalent generic CMOS LCD drivers. Ensure any substitute maintains identical pinout configurations and active-low output polarity to avoid redesigning the display interface circuitry.
