CPC7220K

Overview

The CPC7220K is an analog switch integrated circuit manufactured by IXYS (Littelfuse). It features eight independent single-pole single-throw (SPST) switches. The device supports a maximum on-resistance of 25 Ohms and handles a maximum switch voltage of 160 V. Switching times are limited to a maximum of 5 microseconds for both turn-on and turn-off durations. It operates within an operating supply voltage range of 4.5 V to 6 V, with a maximum supply current of 4 mA. The component is designed for surface mount installation in a PLCC-28 package and functions within a temperature range from -40°C to +70°C.

Feature Summary

• Integrates eight independent SPST analog switches in a single package
• Supports high-voltage signal switching up to 160 V
• Provides fast switching performance with 5 us max on/off times
• Compatible with standard single or dual supply configurations

Applications

• High-voltage signal routing in test and measurement equipment
• Data acquisition systems requiring multi-channel isolation
• Industrial control panels for sensor signal selection
• Communication infrastructure for line switching

Procurement Notes

Verify the specific suffix K against official IXYS documentation to confirm exact packaging and tape-and-reel specifications. Ensure the supplier provides traceability to Littelfuse manufacturing standards. Confirm RoHS compliance status matches the required project constraints. Validate that the PLCC-28 package variant aligns with the PCB footprint design. Request datasheet revision history to ensure compatibility with latest electrical characteristics.

Selection Notes

Select this component when eight isolated channels are required for signals up to 160 V. The 25 Ohm on-resistance suits applications where moderate signal loss is acceptable. Verify that the 4.5 V to 6 V logic interface matches the system controller output levels. Consider the PLCC-28 thermal dissipation capabilities if multiple switches operate simultaneously under load. Compare against lower-voltage alternatives if the 160 V rating exceeds actual signal requirements.

Part Context

The CPC7220 series belongs to IXYS' family of high-voltage analog switches. These devices are engineered for robust performance in industrial environments. The CPC7220K specifically denotes the plastic leaded chip carrier package variant. This series complements other multiplexer and switch solutions offered by Littelfuse for signal conditioning tasks.

Replacement Considerations

Publicly confirmed substitute part numbers for CPC7220K are not available in verified sources. Consult IXYS application notes for cross-reference recommendations based on specific voltage and channel requirements.
