CD4055BE

Display Drivers Overview

The CD4055BE is a CMOS hex BCD-to-decimal decoder/driver belonging to the 4000 series. It accepts a 4-bit binary-coded decimal input and activates one of ten active-high outputs corresponding to the decimal value. The device operates within a supply voltage range of 3V to 18V and features low static power consumption typical of CMOS technology. It includes an internal blanking input for controlling display segments and supports direct driving of LED or LCD indicators without external buffering components.

Display Drivers Feature Summary

• Converts four-bit binary coded decimal inputs into ten mutually exclusive active-high output signals
• Integrates an internal blanking control input to manage display segment activation
• Provides direct drive capability for visual indicators such as LEDs or LCD segments
• Operates across a wide dual-supply voltage range suitable for various logic families

Display Drivers Applications

• Driving seven-segment LED displays in digital readout systems
• Decoding address lines for memory selection in embedded controllers
• Control logic interfaces for industrial instrumentation panels
• State indication circuits in automated testing equipment

Display Drivers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the required DIP-16 configuration. Ensure supply voltage ratings align with system requirements. Check for compliance with environmental standards if applicable. Validate pinout compatibility before integration into existing designs.

Display Drivers Selection Notes

Select this component when a dedicated BCD-to-decimal decoding function is required with minimal external circuitry. Consider the operating temperature range and supply voltage limits relative to the application environment. Evaluate pin count and package size constraints for PCB layout. Compare propagation delays and drive current capabilities against load requirements.

Display Drivers Part Context

This part belongs to the standard 4000 series CMOS logic family, known for wide voltage operation and low power consumption. It serves as a fundamental building block for digital counting and display systems. The device complements other series components like decoders and multiplexers to form complete data processing chains.

Display Drivers Replacement Considerations

Substitute with CD4055B from Texas Instruments for equivalent functionality. Verify pinout and electrical characteristics match exactly. Check package dimensions for mechanical fit. Ensure supply voltage and temperature ranges are compatible.
