MAX4545EPP+

Analog Switches - Special Purpose Overview

The MAX4545EPP+ is a quad, low-voltage, bidirectional RF/video switch designed for 50Ω and 75Ω systems. It contains four normally open single-pole/single-throw (SPST) switches with a T-switch configuration. The device operates on dual supplies from ±2.7V to ±6V or a single supply from +2.7V to +12V. Key electrical parameters include a maximum on-resistance of 20Ω at ±5V, signal-path matching of 1Ω max, and flatness of 0.5Ω max. It provides -80dB off isolation and crosstalk at 10MHz, with a -3dB bandwidth of 300MHz. Logic inputs are TTL/CMOS compatible.

Analog Switches - Special Purpose Feature Summary

• T-switch architecture ensures high-frequency off isolation and low crosstalk
• Rail-to-rail analog signal handling in either direction
• Low insertion loss suitable for RF and video applications
• TTL and CMOS logic compatibility across specified supply ranges

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 'EPP+' against official documentation to confirm package type and temperature range. Ensure the source document matches the manufacturer's current datasheet revision. Confirm that the ordering information aligns with the intended application requirements before finalizing procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring bidirectional switching for RF or video signals up to 300MHz. It is suitable for both 50Ω and 75Ω system impedances. Consider the ±5V optimized performance for best linearity and speed. Verify power supply constraints match the dual or single supply capabilities.

Analog Switches - Special Purpose Part Context

The MAX4545EPP+ belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage analog switches. While the MAX4545 features four SPST switches, the MAX4546 offers two dual SPST configurations, and the MAX4547 provides two SPDT switches. All share similar T-switch construction and performance characteristics.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements within the same family include the MAX4546 and MAX4547, which offer different switch configurations but similar electrical performance. Verify pinout compatibility and functional requirements such as SPST versus SPDT needs before substituting.
