Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm compliance status and availability. Ensure the ordering information matches the exact package type and tape-and-reel specifications required for your assembly process. Cross-reference the part number with official distributor catalogs to confirm active status and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring direct drive for multiplexed LCD panels without external bias circuits. Consider the 1/4 duty cycle capability and segment count relative to the display resolution needed. Evaluate the operating temperature range and supply voltage compatibility with the system's power architecture to ensure reliable performance under varying conditions.

Part Context

This part belongs to onsemi's family of LCD driver integrated circuits designed for general-purpose display applications. These drivers are commonly used in environments where space constraints and power efficiency are critical. The series typically offers robust noise immunity and flexible configuration options for various display types, supporting both common and segment outputs for complex graphical or alphanumeric displays.

Replacement Considerations

Consult onsemi's official cross-reference tools for verified substitute part numbers. Ensure any replacement maintains compatible pinout, voltage levels, and duty cycle support. Verify that alternative components meet the same thermal and electrical specifications for the intended application environment.
