CD22105AE is listed in the Display Drivers range at ChipApex. The manufacturer field lists Harris Corporation. Its product description is FOUR DIGIT LCD DECODER DRIVERS. Review the specifications below when checking this part for your BOM.
The CD22105AE is a four-digit LCD decoder driver manufactured by Harris Corporation. It operates within a supply voltage range of 3V to 6V and utilizes through-hole mounting technology. The component is housed in a 40-PDIP package, designed for driving multi-digit liquid crystal displays in electronic systems requiring dedicated decoding and driving capabilities.
Verify the specific manufacturer source, as Harris Corporation assets were acquired by Renesas Electronics. Confirm RoHS compliance status, as original Harris components may not meet current environmental standards. Ensure the 40-PDIP package dimensions match the target design constraints before finalizing procurement decisions.
Select this component when a dedicated solution for four-digit LCD driving is required without external microcontroller overhead. Consider the 40-pin DIP footprint for legacy board designs. Evaluate the 3V to 6V operating range against system power availability to ensure stable operation under all expected load conditions.
This part belongs to the Harris Corporation line of specialized display interface integrated circuits. It serves as a functional block for converting binary-coded decimal inputs into segment drive signals for liquid crystal displays, simplifying the hardware architecture for numeric display applications in older electronic designs.
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with potential successors from Renesas Electronics or other logic manufacturers if sourcing new production units.
