Display Drivers Procurement Notes

Verify the specific suffix (e.g., BM) confirms the SOIC-16 surface mount package variant. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Confirm that the parallel input configuration aligns with your system's logic levels. Check for any specific environmental certifications such as REACH SVHC status relevant to your region. Validate the active lifecycle status to ensure long-term availability for production.

Display Drivers Selection Notes

Select this component when a dedicated driver for four-segment LCDs is required. Consider the 3V to 18V operating range for flexibility in power supply design. The SOIC-16 package is suitable for surface mount assembly processes. Evaluate the -55°C to 125°C temperature range against your application's environmental conditions. Compare the 0.04 µA supply current against other options for power efficiency.

Display Drivers Part Context

The CD4054B series belongs to Texas Instruments' standard CMOS logic family, specifically tailored for display applications. This part number represents the industrial grade version in a surface mount package. It complements other display drivers like the CD4055B, which handles five-segment displays. The series is known for robust performance in consumer and industrial electronics.

Display Drivers Replacement Considerations

CD4054BE is a pin-compatible through-hole alternative. CD4054BMT offers the same function in a tape-and-reel format for automated assembly. CD4054BPWRG4 is a TSSOP variant, though it may be obsolete; verify current stock status.
