AS1100PL

Overview

The AS1100PL is a serial interface LED driver IC designed for driving seven-segment displays with decimal points. It supports up to eight digits and operates within a supply voltage range of 4V to 5.5V. The device draws 330mA of supply current and functions reliably between 0°C and 70°C. Packaged in a 24-pin DIP, it facilitates direct connection to microcontrollers via serial communication protocols.

Feature Summary

• Supports serial interface control for simplified system integration
• Drives seven-segment displays including decimal point configuration
• Capable of multiplexing up to eight display digits

Applications

• Seven-segment digital display systems
• Industrial instrumentation readouts
• Consumer appliance control panels

Procurement Notes

Verify component status as the AS1100PL is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure design-in timing accounts for potential supply chain constraints associated with discontinued components.

Selection Notes

Select this component for legacy designs requiring serial-driven seven-segment displays. Evaluate alternative active series if new production is required due to obsolescence. Verify pin compatibility and software library support for existing firmware architectures before procurement.
