MAX4545CAP+

Analog Switches - Special Purpose Overview

The MAX4545CAP+ is a quad, low-voltage, bidirectional RF/video switch from the MAX4545 family. It contains four normally open single-pole/single-throw (SPST) switches in a T-switch configuration. The device operates with dual supplies of ±2.7V to ±6V or a single supply of +2.7V to +12V. Key electrical parameters include a -3dB bandwidth of 300MHz, maximum on-resistance of 20Ω at ±5V, and off-isolation of -80dB at 10MHz. It features TTL/CMOS-compatible logic inputs and handles rail-to-rail analog signals.

Analog Switches - Special Purpose Feature Summary

• T-switch architecture for high-frequency isolation
• Bidirectional signal handling capability
• Low power consumption design

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 'CAP+' against official documentation to confirm package type and temperature range. Ensure compatibility with required supply voltages and logic thresholds before integration. Check for RoHS compliance status as indicated in the manufacturer's ordering information.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring quad SPST switching with high bandwidth up to 300MHz. Consider the 20Ω on-resistance and -80dB off-isolation specifications for signal integrity. Verify that the operating temperature range meets system requirements.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4545/MAX4546/MAX4547 series of low-voltage CMOS analog switches. The MAX4545 specifically provides four independent SPST channels, distinguishing it from the dual-channel configurations of the MAX4546 and MAX4547 variants within the same family.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements within the same family include the MAX4545CPP and MAX4545CWP. Verify pinout compatibility and ensure the substitute part matches the required operating temperature range and package dimensions.
