MAX4545CWP+

Analog Switches - Special Purpose Overview

The MAX4545CWP+ is a quad, low-voltage, bidirectional RF/video switch in a 20-pin Wide SO package. It contains four normally open SPST switches with a DC to 300MHz bandwidth and -80dB off isolation at 10MHz. Operating from ±2.7V to ±6V dual supplies or +2.7V to +12V single supply, it features a maximum on-resistance of 20Ω (±5V), 1Ω channel matching, and 0.5Ω flatness. TTL/CMOS-compatible inputs ensure logic compatibility.

Analog Switches - Special Purpose Feature Summary

• Bidirectional T-switch architecture for high-frequency signal routing
• Rail-to-rail analog signal handling capability
• TTL and CMOS logic input compatibility

Analog Switches - Special Purpose Applications

• RF switching
• Video signal routing
• High-speed data acquisition
• Test equipment
• ATE equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CWP+' against the manufacturer's current datasheet to confirm the commercial temperature range and plastic wide SOIC packaging. Ensure the ordering code matches the exact pin configuration required for the target circuit design before finalizing procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a quad SPST configuration is required for video or RF applications up to 300MHz. The device is optimized for ±5V operation; verify that the system power supply aligns with these requirements to maintain specified on-resistance and isolation performance levels.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage CMOS analog switches. While the MAX4546 offers dual SPST configurations and the MAX4547 provides dual SPDT switches, the MAX4545 specifically integrates four independent normally open channels within a single integrated circuit package.
