MAX4545EWP

Analog Switches - Special Purpose Overview

The MAX4545EWP 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. Operating from ±2.7V to ±6V dual supplies or +2.7V to +12V single supply, it features a maximum on-resistance of 20Ω at ±5V, 1Ω matching, and 0.5Ω flatness. Key performance metrics include -80dB off isolation and crosstalk at 10MHz, turn-on time up to 200ns, and turn-off time up to 120ns. The device supports rail-to-rail analog signals and offers TTL/CMOS 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 'EWP' against official documentation to confirm the exact temperature range and package variant. Ensure that any ordering suffixes do not alter the functional specifications unless explicitly stated in the manufacturer's datasheet. Cross-reference the component details with the original Analog Devices source material to guarantee accuracy before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring bidirectional switching of RF and video signals up to 300MHz. It is suitable for 50Ω and 75Ω systems. Consider the power supply requirements, as performance degrades significantly when operating away from the optimized ±5V condition. Verify that the required switching speed and isolation levels meet the system specifications.

Analog Switches - Special Purpose Part Context

The MAX4545EWP belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage CMOS analog switches. While the MAX4545 provides four SPST switches, the MAX4546 offers two dual SPST switches, and the MAX4547 provides two SPDT switches. All variants share similar electrical characteristics and are designed for high-frequency signal routing in compact packages.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX4546 and MAX4547, which offer different switch configurations but similar performance. Other compatible parts may exist, but verification against the official datasheet is required to ensure pinout and electrical parameter compatibility.
