Display Drivers Procurement Notes

This component has reached end-of-life status and is no longer actively manufactured by onsemi. Availability is limited to existing stock held by distributors or third-party suppliers such as Rochester Electronics. Verification of part authenticity and storage conditions is critical due to the obsolete nature of the device. Buyers should confirm lead times and lot dates carefully when sourcing from secondary markets.

Display Drivers Selection Notes

Engineers replacing this obsolete part must evaluate alternative LCD drivers that match the 88-segment capacity and 36-SOP footprint. Compatibility checks should include verifying serial interface protocols and supply voltage ranges between 2.7V and 6V. Thermal performance within the -40°C to 85°C range must be validated against the new component's specifications to ensure reliable operation in the target application environment.

Display Drivers Part Context

The LC75844M-E belongs to the LC75844 series of LCD drivers produced by onsemi. It is part of the company's standard product portfolio focused on display driving solutions. The device utilizes BCD technology common in onsemi's analog and mixed-signal platforms. As an obsolete component, it represents legacy design choices for segment-based LCD applications previously supported by this specific product line.

Display Drivers Replacement Considerations

No direct public substitute part numbers are confirmed for the LC75844M-E. Designers should consult onsemi technical support for potential pin-compatible alternatives or consider redesigning with modern LCD drivers that offer similar segment counts and interface types while ensuring availability.
