ACPL-W21L-500E

Overview

The ACPL-W21L-500E is a single-channel high-speed optocoupler from Broadcom's ACPL series, housed in a 6-pin SOIC surface-mount package. It features a digital CMOS input and a logic gate output, designed for low isolation applications. Key electrical parameters include a maximum data rate of 5 Mb/s, an insulation voltage of 5000 Vrms, and a typical propagation delay skew of 220ns. The device operates with a maximum low power supply current of 1.1mA per channel and supports a minimum low forward current of 1.6mA. It functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a digital CMOS input stage with a logic gate output for high-speed signal transmission.
• Provides robust electrical isolation rated at 5000 Vrms between input and output circuits.
• Optimized for low power consumption with a maximum supply current of 1.1mA per channel.

Applications

• High-speed logic interface circuits requiring galvanic isolation
• Digital communication systems utilizing low isolation standards
• Industrial control systems needing fast signal transfer

Procurement Notes

Verify the specific suffix '500E' to confirm the tape-and-reel packaging configuration, as other suffixes may indicate different quantities or lead-free status. Ensure the procurement documentation explicitly lists the 5000 Vrms insulation rating and 5 Mb/s data rate to match design requirements. Cross-reference the manufacturer part number against official Broadcom distribution channels to avoid counterfeit components.

Selection Notes

Select this component when a high-speed interface (up to 5 Mb/s) is required alongside moderate isolation levels (5000 Vrms). It is suitable for designs prioritizing low power consumption, given the 1.1mA supply current. Consider the 6-pin SOIC footprint for PCB layout constraints. This part is appropriate for general-purpose digital isolation where automotive qualification is not mandatory.

Part Context

This device belongs to the Broadcom ACPL series of optocouplers, which are engineered for various isolation needs. The ACPL-W21L variant specifically targets high-speed digital applications using CMOS technology. It complements other parts in the family that may offer higher isolation voltages or different output types, such as photodarlingtons, while maintaining a compact surface-mount form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative high-speed optocouplers by comparing pin configurations, isolation ratings, and data rates directly with the manufacturer's datasheet before substitution.
