APS1241SX

Overview

The APS1241SX is a high-speed logic output optoisolator manufactured by Panasonic Electric Works. It features an AlGaAs LED coupled to a photodiode receiver with integrated circuitry, supporting data rates up to 20Mbps. The device utilizes a push-pull or totem pole output configuration for efficient signal transmission. It provides electrical isolation of 3750Vrms between input and output channels. The component is housed in a compact surface-mount package measuring 4.4x4.3x2.1mm, designed for low input voltage operation and reduced power consumption.

Feature Summary

• High-speed communication capability with integrated receiver circuit IC
• Low input voltage and low power consumption design
• Push-pull/totem pole output structure for robust signal integrity

Applications

• Industrial motor control systems
• Motion controllers
• AC servo motor interfaces
• Brushless motor drives

Procurement Notes

Verify the current lifecycle status before procurement, as the APS1241SX is designated as Not Recommended for New Designs (NRND) by Panasonic. Confirm availability through authorized distributors, noting that stock levels may be limited due to the end-of-life designation. Ensure the specific suffix matches the required packaging quantity if ordering from tape-and-reel sources.

Selection Notes

Select this component when high-speed digital isolation is required for industrial automation applications. The integrated receiver circuit simplifies design compared to discrete photodiode solutions. Consider the NRND status carefully; alternative parts within the same Panasonic series should be evaluated for long-term supply chain stability. Verify voltage isolation requirements match the 3750Vrms specification.

Part Context

This part belongs to Panasonic's high-speed photo coupler family, specifically designed for demanding industrial environments. It complements other motion control components like AC servos and brushless motors. The APS series generally focuses on speed and reliability, distinguishing itself from standard logic isolators through its integrated receiver architecture and high data rate capabilities.

Replacement Considerations

Due to the NRND status, direct substitutes should be identified from Panasonic's current high-speed optocoupler lineup. Verify pin compatibility and isolation voltage ratings when selecting alternatives. Cross-reference with newer generation devices that offer similar 20Mbps performance and push-pull outputs.
