AS1108PL

Overview

The AS1108PL is a discontinued LED display driver integrated circuit manufactured by ams OSRAM AG. It features a 20-DIP package and supports 7-segment plus decimal point configurations for 4-digit displays. The device operates on a serial interface with a supply voltage range of 4V to 5.5V and draws 330 mA of supply current. It is designed for surface-mount or through-hole applications within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports 7-segment LED displays with decimal point control
• Utilizes a serial interface for data transmission
• Designed for low-voltage operation

Applications

• LED display modules
• Digital readout devices
• Instrumentation panels

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification of final availability through authorized distributors is required, though stock is likely limited. Designers should confirm RoHS compliance status and check for any pending product change notices before initiating procurement processes for legacy systems.

Selection Notes

Engineers requiring active replacement components should evaluate newer generations from the AS1100 series or other compatible 7-segment drivers. Selection criteria must account for the transition from the obsolete 20-DIP package to modern surface-mount alternatives while maintaining pin compatibility and electrical specifications for existing PCB layouts.

Part Context

The AS1108PL belongs to the AS1100 family of LED drivers produced by ams OSRAM AG. This family focuses on cost-effective solutions for driving multi-digit 7-segment displays in consumer electronics and industrial equipment. The specific PL suffix indicates a PDIP package variant, distinct from SOIC or QFN packages found in other series members.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must consult official ams OSRAM channels for qualified replacements due to the EOL status.
