CD4054BF

Display Drivers Overview

The CD4054BF is a CMOS LCD driver manufactured by Harris Corporation, belonging to the 4000/14000/40000 series. It features a ceramic DIP-16 package and operates within a temperature range of -55°C to +125°C. The device supports a supply voltage of 3V to 15V with a maximum clock frequency of 8 MHz. It includes an internal oscillator and is designed for driving single-digit, four-segment LCDs.

Display Drivers Feature Summary

• Integrated internal oscillator eliminates external timing components
• Supports direct drive of single-digit, four-segment liquid crystal displays
• Capable of operating across extended industrial temperature ranges

Display Drivers Applications

• Driving single-digit, four-segment LCD indicators
• Industrial control panel displays
• Instrumentation readouts

Display Drivers Procurement Notes

Verify component authenticity as Harris Corporation has undergone corporate restructuring. Confirm that the specific marking corresponds to original Harris production rather than subsequent licensees or generic equivalents. Ensure the ceramic package integrity matches the specified R-CDIP-T16 form factor.

Display Drivers Selection Notes

Select this component when a dedicated LCD driver with an integrated oscillator is required for simple segment displays. It serves as a legacy alternative to modern microcontrollers for basic indication tasks. Verify compatibility with existing 4000-series logic families in the design.

Display Drivers Part Context

This part belongs to the standard CMOS 4000 series logic family produced by Harris Corporation. It is functionally equivalent to the industry-standard CD4054B specification. The BF suffix typically denotes the specific ceramic DIP packaging variant offered by the manufacturer.

Display Drivers Replacement Considerations

The CD4054BE (Texas Instruments) is a documented functional substitute. Other variants such as CD4054BM are available from different manufacturers but may differ in package type.
